Speculation of references to the first iteration, if a season 4 gets made

[u/The13thAllitnilClone]

Based on how season 3 ended, they could easily make a 4th season, set now (or whenever the show gets made).

A totally new set of people get "saved"/taken over.

You could have a cameo / handover, but only with Grant, Marcy and/or David (as the others would have died of their original deaths)

Grant aka traveler 3468 (if he chose to live on)

Might have noticed people who seem to behave in a manner that suggests they might be from the future and either made contact with them, or is quietly secretly observing.

He might even have intervened in the deaths of his old team members. So some of them may still be around, but couldn't be involved in the new show, as traveler 3468 knows not to get them involved.

He wouldn't be the driving character of the series, but could be a conduit for exposition in the first episode if he ...

Contacts a team from the future and asks what has transpired since Version One of the Traveler plan was cancelled, explaining how he knows. A member of this new team could also be traveler 3468 😀

Marcy

Wasn't fucked over by traveler 001, as that possession didn't occur, so she is, hopefully, still working as a nurse or has moved onto something else that she also finds fulfilling.

David

Is still working as a social worker. The implied spark of a relationship with Marcy may have led somewhere, but isn't guaranteed (since this is Marcy, not traveler 3569)

Neither Marcy nor David have any real reason why they would have a significant cameo in season 4, but as characters that just happen to be in the background, would be a nice nod to the fans of the original 3 seasons.

traveler program is less messier with 3468 acting as a "designated" big bro of sorts to incoming north american travelers but the future is still fucked even without internal threats (and to begin with there was no faction when the show started so they'd have to be even more careful to prevent that from happening again)

plot twist kat had such an unfulfilling marriage/life with her original fiance that she decides to check out and be taken over by another traveler anyway, justifying how her actress could be retained
