In Terminator: The Sarah Connor Chronicles season 2 Episode 21 (Adam Raised a Cain), John connor, Sara Connor, Derek Reese and Cameron come to Catherine Weaver's building to save Savannah Weaver. In this rescue mission Derek Reese is killed by a Terminator. This incident happens in the year 2007.

So in last episode of season 2 John Connor and Catherine Weaver went to the future and then John found and met "Derek Reese" with the resistance army. So my question is, if Derek Reese died in 2007, how is it possible that he is alive in the future?

All these incidents are happening on same time line and the same earth.

It is a younger pre-time-travel Derek.

A fews things about the future John Connor and Catherine Weaver travel to:

  • It is a future where John Connor is not the leader of the resistance, and might not possibly even exist.
  • It is the future, but before Kyle Reese travels back in time (and therefore before Derek Reese travels back)
  • Derek Reese hasn't aged, he clearly isn't the same one who was shot and killed, otherwise he would be older.

"All these incidents are happening on same time line and the same earth."

That is false. In fact, we see conflicting timelines just in Season 2 with the introduction of Jesse. She has different memories of events and potentially a different Judgement Day date than Derek does. For instance, she says Derek was tortured by Charles Fischer, though Derek doesn't appear to have any memory of this.

  • Jack, as per your answer now i have a question.. is that means in Terminator show's talking about "PARALLEL EARTH"

    @RANSARA009 I don't know about Parallel Earths, but there are clearly ever shifting and conflicting timelimes happening in the movies and the tv show. Aug 10, 2016 at 18:40

It doesn't even need to be a younger pre-time travel Derek. At least up to this moment in the future, John Connor has been missing from history ever since the moment he departed with Weaver to travel to the future. So he would not have sent Derek back in time at all, at least not yet. So Derek is still present. A Derek died in the past, but that was a Derek that had come back from a different future as compared to the one John has created for himself by travelling forward.
