Events changed by the arrival of the T‑X

Notes on Chronology 6

We can see the fruit of John's careful thinking about changing the past. This chronology is identical to the last except for the arrival of the T-X in 2004, an action taken by Skynet. John's actions resulted in exactly the same chronology as before.

Obviously, John must go through the same revelations and come to the same conclusions about the changes to the past he has made. This is one of the reason that sending Kyle back with the 1997 date is so crucial. It is the fact that Kyle told Sarah Judgment Day happens in 1997 and it actually happens in 2004 that starts John off in the process of thinking about the effects on the past.

We know that John and Kate somehow survive Judgment Day. They also manage to evade the Terminator sent back to kill John's lieutenants (Kate is on that list).

So, the T-X is working its way through the list of lieutenants when it comes across Kate's name. It seems likely that it would attempt to locate her at her apartment first rather than at the clinic. It would find her fiance and kill him and take his form. It may simply wait for Kate to show up, or it may decide that, since she is not home, she is probably at work and so goes to the clinic.

Now, Kate encounters John and locks him in the cage. Hercules, with a hairball, arrives. Kate lets John know that she remembers him. The Terminator does not show up at this point, being at Kate's apartment. So, Kate treats the cat and, after the customer leaves, she lets John out of the cage. Because it is possible that the Terminator comes to the clinic after not finding Kate at home, and we know that John and Kate survive, they must have left the clinic before the Terminator arrives. Possibly just to go to breakfast and reminisce about the good old days at West Hills Junior High.

Regardless, somehow John and Kate evade the T-X and remain together until the bombs fall.
