Continuum, Time Travel and The Grandfather Paradox

The last episode to Continuum’s second season (“Second Time”) sees a grief stricken Alec Sadler (Erik Knudsen use the time travel device to go back in time to save the life of Emily (Magda Apanowicz). A shocked and distraught Keira (Rachel Nichols) looks on as Alec disappears from the time line in a flash of light. What is everyone’s favorite Protector to do now that the time travel device no longer exists? Is she forever trapped in the present unable to do anything about Alec’s betrayal?

If you were hoping to find out what Kiera would do now that she is stuck in the present then don’t hold your breath. Alec reemerges in the past–one week in the past to be exact–to create a new timeline while Kiera is captured by the Freelancers. The original timeline, as explained by Head Freelancer Catherine (Rachael Crawford) no longer exists. The intense roller-coaster ride and the jaw-dropping events of the last season, from the pinning of Agent Gardiner’s (Nicholas Lea) murder on Kiera to Carlos Fonnegra (Victor Webster) leaving the Vancouver Police Department to join Julian (Richard Harmon) and Liber8 never happened.

So what are Continuum fans to do? Are we simply to ignore the last episodes of Season Two as if they never happened? That remains an open question.
The Season Three premier certainly continues with the same action packed intensity from which the last season ended but it does something else–it explains the time travel rules upon which the show is based. It also appears that the show’s writers have put a lot of thought and effort into ensuring that these rules are as consistent as possible, especially where the issues of paradoxes are concerned.

The Paradoxes of Time Lines

Continuum Time Travel

Head Freelancer Catherine explains that time travel is not immutable and is like a brancing tree that needs to be pruned.

“Destiny is not set. Time is not immutable. The continuum is like a tree. It can grow wild or it can be cultivated.”

In the premier episode, head Freelancer Catherine explains the concept of timelines and the physics of time travel to Kiera. While there is only one timeline, it can be changed. Go back far enough in time and you can change everything to create an entirely new and different timeline.

This answers some of the paradoxial questions of the last two seasons, if Maddie (Olivia Ryan-Stern) was really Kellog’s (Stephen Lobo) grandmother, then why didn’t he pop out of existence in the current timeline. One idea put forward by Alec was that she may not have been Matthew’s grandmother. It turns out she could have been and to understand why, we must look into how Continuum’s physics of time travel resolves the Grandfather Paradox.

The Grandfather Paradox


The grandfather paradox is one of the more well-known time travel paradoxes and was first described by the science fiction writer René Barjavel in his 1943 book “Le Voyageur Imprudent(Future Times Three). In this scenario, our time traveler goes back in time before his grandfather is married and kills him. The paradox is that the time traveler is never born and can not go back in time to kill his grandfather. His grandfather is free to meet the grandmother, get married, have kids and our time traveler is eventually born. When the time traveler gets older, he steps into his time-machine and goes back in time to kill his grandfather. This cycle continues ad infinitum and without resolution.

Recognizing this vulnerability, in the Season One episode “A Test of Time”, Kagame (Tony Amendola) decides to test this paradox and possibly get rid of their “Protector problem” once and for all. Liber8 start by killing young women with Kiera’s grandmother’s name–“Lily Jones”. During the course of the episode Liber8 take additional insurance by planning to kill Kellog’s grandmother; revenge against Kellog for helping Kiera. Travis (Roger Cross) shoots Kellog’s grandmother and everyone sees that Kellog does not disappear–the grandfather paradox does not apply to them. Or does it?

According to Catherine’s explanation of time travel, killing Maddie creates a new time line. In this new timeline Kellog will not be born and many of the events in Kellog’s life, from his meeting Kiera to his part in Liber8 will never happen. In a sense the very timeline that Kiera so desperately tries to protect no longer exists but this doesn’t mean that Kellog’s absence changes things so completely that the future Kiera and the Freelancers are trying to protect never happens. Kiera’s primary concern is her family but everything can still go according to plan even though Kellog no longer exists in the new timeline.

Catherine and the Freelancers appear to subscribe to the Great Man Theory, a 19th-century idea in which history can be explained by the impact of “great men”, or heroes. As Kellog is not one of these supposed “great men” then many key events, such as Alec’s rise to power and discovery of time travel, will still happen. This means that Kiera’s family will still exist in the future. As they don’t know who Kellog is, they will also be completely unchanged by the ripple effect of Maddie’s death. The reason Catherine and the Freelancers aren’t too concerned of Maddie’s death is because her impact on the future is negligible–her life or death changes nothing. Talk about a major blow to one’s ego.

Resolving the Grandfather Paradox

Continuum’s time-travel physics provides a logically consistent way to resolve the Grandfather Paradox. A time traveler who kills his own ancestor or whose ancestor is murdered won’t vanish from existence. Rather, the timeline he came from will disappear to be replaced by a new timeline in which he will never be born. As our time traveler is a refugee from the previous timeline that no longer exists, he won’t pop out of existence and is safe from the ramifications of the Grandfather Paradox.

This single and mutable timeline idea not only overcomes the logical paradox and inconsistencies of the Grandfather Paradox but others as well , such as the Bootstrap and Predestination Paradoxes–something we will examine in future blog posts. It also highlights how dangerous time travel is in the series. As time is not immutable, a nefarious time traveler can use a time machine as a weapon to mold the future to achieve for personal gain. Jason has hinted that the Freelancers have meddled with humanity’s history before. The extent of this meddling remains to be seen.

The Freelancers have the power to monitor the continuum and stop people from making these changes to the timeline but this doesn’t mean they are the good guys. Catherine has admitted they see themselves as guardians to the continuum, in essence, the ones who “prune” the tree. This makes you wonder whose interests they represent and whether those interests are the best for everyone. This is interesting because the series has yet to really identify who the good guys and bad guys really are.

While we may at times root for Kiera, as the series progresses we may discover we never should have. We have two Alecs in this timeline. In the last timeline we have seen hints that Alec could be turning to the “dark side” and become the man to usher in a totalitarian and dystopian future of 2077. All that may have been changed with Emily’s death. It is amazing the difference a week makes. Could we see Alec Sadler fight on both sides of this temporal war? Your guess is as good as mine.

Time Loops and the Paradoxes of Continuum’s Time Travel Physics

The season finale to Continuum leaves the viewer with lots of surprises and questions that are sure to keep them engaged until Season Three begins in 2014. While Season Two doesn’t specifically answer questions regarding the rules to time travel used in the show, it does provide some hints and insights on what might be happening. If anything we can be certain that the rules are going to be as complex and interesting as the plot so far. To get up to speed you should read my first article, “The Wibbly-Wobbly of Continuum“.

Future Alec sends everyone back

We learn at the end of Season One and the start of Season Two that the future Alec (William B. Davis) is responsible for sending everyone back in time. It also turns out that there is a specific reason for sending Kiera back – to either prevent the future from happening or to prevent him from going down a certain path. It is apparent that future Alec regrets many of the things that have taken place when he tells his son, Jason (Ian Tracey), “Liber8 wouldn’t exist if it weren’t for me. Perhaps they are just a manifestation of my conscience.”

But Kiera’s presence isn’t without problems. Escher/Marc Sadler (Hugh Dillon) berates Kiera when he tells her

“You carry destruction in your wake, you’re the time bomb.”

Given that Escher is a former Freelancer, he may have some insight from his former occupation. Warren (Adrian Holmes), one of the enigmatic “Freelancers”, also hints that Kiera’s presence is an “anomaly” and a “glitch in the continuum” and it appears that Warren was ready to kill Kiera to “fix” things.

This raises several questions. If Kiera is a problem, why was she sent back in the first place? Did future Alec know of the trouble she would cause when he sent her back? In Season One, we witness the the “first” meeting between the future Alec and Kiera and it seems that he knew who she was. So while this was a first time meeting for Kiera, it certainly isn’t for Alec.

We Know Things can change

Freelancers and Continuum

Kiera meets with fellow time traveler Jason, who informs her that he’s being followed by other time travelers from the future he calls “Freelancers.”


One of the mysteries behind the show’s time travel physics is whether there is a single timeline or multiple ones. If there is a single timeline, for events to happen as they are supposed to, they must follow the Novikov self-consistency principle. This principle asserts if an event exists that would give rise to a paradox, or to any “change” to the past whatsoever, then the probability of that event is zero.

This means that for the events that leads up to Liber8’s trip back in time, then all the events in the past need to lead up to that one event. Alec can’t decide not to send Liber8 back in time as doing so ironically creates the corporate run future. In short, this makes it impossible to create time paradoxes which is different from a multiple timeline scenario where anything can happen. In this case, when Kiera and Liber8 arrive in 2012, they create a new timeline that has no impact on the timeline they came from.

In “Second Thoughts” (Season 2, Episode 3), Jason tells Kiera about the Freelancers and that Escher is also one of them. It’s not clear if Jason knows that Escher is his grand-father but it is likely. He seems to think that Escher is dangerous and not a person to be trusted. Jason also tells Kiera that:

“You know, you won’t be the same person when you left”.

This is one of the clues that might be telling us that we are dealing with a single timeline. If a person was to return to the 2077, they might take the place of their “double” and that person’s memories will eventually be replaced by new memories of the new timeline as if the old one never happened.

This gives credibility to the “time loop” theory of a single timeline. But the implication of a single timeline has always been that for the events that lead Liber8 to arrive in 2012, then everything must lead up to them being sent back in time in 2077. Jason could be saying this doesn’t have to be the case; everyone doesn’t have to follow a particular script.

The fact that things can be changed becomes all the more clear in “Second Truths” (Season 2, Episode 6). Kiera solves and stops a serial killer whose case file was unsolved in 2077 in future. Using information gleaned from the future is an example of the Bootstrap Paradox where information sent back from the future becomes the very information that was brought back in the first place.

The Bootstrap Paradox is problematic as it implies that the information was never created. It exists specifically because the loop occurs. This episode is important because it establishes one thing — paradoxes are possible in the Continuum Universe. This means that we don’t have to stick to Novikov even if we are dealing with a single timeline.

As her memories remain unchanged upon solving the case, then according to Jason, she won’t experience any changes to her memories until she returns to 2077. The events of her examining the unsolved cold case in the future have been wiped out and no longer exist. We don’t know what events have replaced of that day. All we know is that it didn’t happen. This has some profound repercussion for Kellog.

What this means if or when she returns, remains to be seen. The multiple timeline scenario posed one problem. If 2077 Alec sends Liber8 back in time, he can never achieve his plan to stop the dark path the world has taken as he will only change the history of an alternate Universe.

The time loop scenario poses a similar problem. If all the events must happen in a way that must lead up to Liber8’s “execution”, then there is no way Alec can change the past. Allowing paradoxes to be a part of the show’s time travel physics solves that problem and allows Alec to hatch the plan he needs to save the world.

Garza kidnaps a young Alec

In “Second Wave” (Season 2, Episode 10), Jasmine Garza(Luvia Petersen) kidnaps young Alec on the orders of his future self. It seems this was future Alec’s contingency plan in case the corporate controlled future appears imminent. Unfortunately, it seems that in an act of desperation and frustration, Garza jumped the gun and acted prematurely.

Continuum Time Travel Alec and Jason

In 2077, the older Alec tells his son Jason of his plans to send Liber8 back in time to stop the corporate controlled future.


It seems that this isn’t the only plan the future Alec has put in motion. In the season finale, “Second Time”, we learn that Jason is his son and not his father as previously believed. In this scene, future Alec says:

“Because you will inherit my failure if I don’t succeed and I don’t wish that on anyone”

Could it be that he means that if he fails and is killed, Jason will be wiped out of existence when he returns to the future?

It also seems that a time traveler won’t feel the effects of his actions until he returns to the future timeline. Jason tells Kiera that:

One day, you’re going to wake up and wonder if any of it really happened.

This may mean that once they return to the future, they not only replace their future selves but eventually take on the experiences and memories of that time line as if they never went back in time.

This provides some insights to the “A Test of Time” (Season 1, Episode 5) episode when the young girl believed to be Kellog’s (Stephen Lobo) grandmother is killed by Travis. Whether this girl is really Kellog’s grandmother or not is never answered but we always assumed that as Kellog didn’t pop out of existence then Kellog was mistaken. It turns out that if Maddie (Olivia Ryan Stern) really is Kellog’s grandmother, he may pop out of existence upon his return to the future.

This also has some repercussions for Kiera herself. In the last few episodes of Season 2, Kiera has become almost obsessed with returning to 2077 and to be with her family despite Alec explaining that so many changes have happened that the future she knows may not even exist. Her best bet at ensuring the existence of her family is to stay in 2013 and see her predicament through.

What happens in the future doesn’t stay there

It would seem that whether there is one universal time-line or multiple ones lies somewhere in the middle. Escher calling Kiera the “time bomb” and Warren referring to her as a “glitch” indicates this. It seems that Kiera’s very presence is problematic.

Kiera’s presence also makes you wonder who the Freelancers are and their true goals and mission. According to Jason, humanity’s history has been guided by this enigmatic group as they seed the past with the technology that enables mankind to make the next leap froward; another example of the Bootstrap Paradox. When Warren describes his mission to Jason, we are lead to believe that the Freelancers might be the good guys — the equivalent of time cops.

But Jason believes this group is bad and might comprise individuals who manipulate history for their own benefit. It’s not clear whether Jason knew of the Freelancers before his meeting with Warren in 2077 or he picked up information about the group when he arrived in 1990. We were lead to believe that Jason’s arrival in 1990 was accidental but could his father have sent him back to investigate the circumstances of his birth and find out more about the Freelancers? Could he have discovered the existence of rogue Freelancers like Escher in the process and hence the reason why he believes his grand-father is dangerous?

As future Alec knows of the Freelancers, this could mean that this isn’t the first time any of this is happening. Not only does he know of the Freelancers from past experience but it may have happened several times in the space-time continuum — he just doesn’t “remember” it. Escher may have gone back in time to start Pyron, thereby creating the catalyst that will lead to the eventual creating of Sadtech and the dystopian corporate controlled future. This also leads young Alec to create the time-travel device and start the “family business”.

As the Freelancers are known to “interfere” in humanity’s development, it could mean that the Freelancers meant for the corporate controlled future to happen. This isn’t without consequences. Alec, realizing the horrible mistake he has made, sends Liber8 back in time to prevent this. But if the future is changed by events in the past, how would he know he has succeeded or that he even made an attempt in the future? The best way is to send a message in a bottle and this is where Kiera come in. He uses Kiera’s Mark 4 polymeric nano-composite body armor to save that message and this is where the time loop theory becomes intriguing. If this has happened before then he can send the information he needs to change the future. He can send his past and future selves the information they need, telling them what worked and what didn’t.

Time Travel in Continuum

Kiera is held prisoner in Continuum

In an unknown location and time, Kiera is held prisoner by the Freelancers with her fellow time travelers, their fates uncertain.


It seems that Contonuum’s time travel physics utilizes a single timeline. Travel back in time creates a new timeline that wipes out the old one. In several episodes, we see Kiera being dragged to a futuristic holding cell. At first, we are lead to believe that this might be a hallucinatory effect of future Alec uploading a file into Kiera’s memory but it seems that these hallucinations are very real and might be a Freelancer controlled prison.

We are never told where or even when this prison cell is. All we know is that the Freelancers are kidnapping other time-travelers. What they do with them after they are captured is anyone’s guess. If they return them to their proper place in the time line, could Kiera’s nightmares be a result of her remembering her traumatic capture from a previous time line? Or maybe she is remembering some event that is supposed to happen. The revived Curtis Chen (Terry Chen) offers no clues.

In the season’s finale, Warren and Curtis talk about “this timeline”. This indicates that the events with Liber8 and Kiera have happened several times. Exactly what the Freelancers do with their prisoners is unanswered. Do they “reinsert” them or do they keep them captive? Can we expect several prison cells all holding different versions of everyone? Are these doppelgangers connected in any way?

Fans of the show know that there is nothing easy when it comes to understanding the show. The seemingly basic premise of the “evil” Liber8 fighting to stop the distopian future hides a much deeper plot. By allowing paradoxes to be a part of the show’s physics, it appears that a much deeper plot exists — a battle between Alec and the Freelancers and where their battle is a game of chess played across space and time. The question is, are everyone just pawns or is there a bigger eventual battle where everyone plays a part to come?
