That's what I've been saying this whole time. That's why T2 can happen. If T1 can happen with the weird "what came first, the John Connor or the Kyle Reese" problem, then T2 is valid.
This is how I see it,
Timeline 1
- (hypothetically) Sarah Connor gets pissed that she's stood up by her boyfriend. She goes off to that pizza place or whatever, and maybe, by fate, goes to Tech Noir. She finds some dude and has a one night stand with him. She gets knocked up and has a son, John Connor. Through a variety of reasons and circumstances, she becomes disgustingly militant. That passes on to John. While this is happening, Skynet is invented by Cyberdyne Systems. It becomes self aware and Judgment Day happens. John is one of the survivors, he's sent to those extermination camps/prisons where he has to dispose of fellow humans. There he meets Kyle Reese, a fellow prisoner. John's background allows him to break out of the camps and rally a rag tag resistance that includes Reese. Decades of fighting ensues. John and his team find out that Skynet sent a Terminator back in time as a last ditch effort to defeat Connor. Connor needs a volunteer to go back in time, Kyle Reese who wants a chance at "meeting the legend" and some soldier named Sumner (
Deleted Scene from T1) volunteer and go back in time. John gives Reese and Sumner a photo so they have a face to the name. After decades of fighting, the resistance storms Skynet's compound, smashes it's defense grid and win. John sends Reese and Sumner back.
Timeline 2
- The Terminator, Reese and Sumner arrive in 1984. Sumner dies when he's fused to objects in the alley way
(Deleted Scene from T1). Sarah Connor gets pissed that she's stood up by her boyfriend. She goes off to that pizza place then sees the Sarah Connor killings. She goes to Tech Noir after being stalked by Reese. It plays out like the film shows. Sarah and Kyle have sex, Kyle dies, the Terminator gets crushed, etc. Sarah goes into hiding, training John. Judgment Day happens, John has extensive knowledge on the war now thanks to Reese circumventing the time line and becoming his father. Now when he meets Reese, he doesn't see him as a buddy, but as his dad. Now he HAS to send Kyle back to exist as his current self. They win the war, yadda, yadda, yadda, Kyle Reese is sent back in time
thinking he volunteered. Since Connor doesn't know about Sumner, there's no point in sending him too.
Timeline 3
-
The Terminator film as we know it. The Terminator and Reese arrive in 1984. Sarah Connor gets pissed that she's stood up by her boyfriend. She goes off to that pizza place then sees the Sarah Connor killings. She goes to Tech Noir after being stalked by Reese. It plays out like the film shows. Sarah and Kyle have sex, Kyle dies, the Terminator gets crushed, etc. Cyberdyne finds the arm and chip from the Terminator. This expedites the development of Skynet. Miles Dyson is brought on board. Sarah goes into hiding and trains John to be a great "military leader". She then tries to blow up a computer factory and is sent to Pescadero. Since she knows Judgment Day is two years away thanks to Kyle, she escapes, takes John back (against his will) and they go into hiding. Judgment Day happens. John has extensive knowledge on the war now thanks to Reese circumventing the time line and becoming his father. Skynet is even more advanced than prior iterations of Skynet thanks to the arm and the chip from the Terminator. Now when Connor meets Reese, he doesn't see him as a buddy, but as his dad. Now he HAS to send Kyle back to exist as his current self. Likewise, Skynet HAS to send the Terminator back to exist in it's current state. Now that it's more advanced, the T-1000 is the newest/latest prototype and it sends it back to 1995 to kill a young John Connor, just in case the T-800 fails to kill Sarah. John finds out about this new development. They win the war, yadda, yadda, yadda, Kyle Reese is sent back time
thinking he volunteered. Since John Connor never knew about the T-1000 until the last minute, he and his men send back a reprogrammed Terminator to protect him. So now, Skynet just doesn't send the T-800 back, but a T-1000 as well (for added measures). Likewise, John just doesn't send Reese back, he sends the last ditch, reprogrammed T-800 back as well.
-
Terminator 2 as we know it. Plays out like in the movie. Now that the T-800 and T-1000 are thrown into the mix, this is literally the FINAL battle. Now that Sarah and John have the reprogrammed T-800, they know who is responsible for Judgement Day. If the T-1000 and T-800 weren't sent back, Sarah would have still escaped Pescadero, found John and hid. Since the reprogrammed T-800 intervened, they're able to destroy Cyberdyne Systems and all of it's research, Skynet no longer exists. The End.
