"OK, I am new here so maybe there is a sticky for things we know to be facts, but since I don't see one I think we should start one. You don't have to post obvious stuff, but if you believe a fact in question to be true you should post it here and offer some evidence for support. I'll go first.

1) Riley is definitely from the future.
Evidence: She tells Jesse in the dress shop "There are a lot of mirrors in this world" and at the house she tell the family "You are all dead"

2) Future john is still around 16-17 years old.
Evidence: Derek was looking at the time machine room and John walks up behind him. He is still 17 years old, then Derek turns and sees him and wakes up to John's voice. Also, when he is coughing up blood he has his eyes closed and goes "Where's Kyle, where did you send him?". He then opens his eyes and looks right at young John and says "Where is he? You owe me the truth" like he is still talking to future John. Also, the fact that he is only seen by a handful of people in the future is probably because they would never follow him if they knew he was just a kid."

"1. Judgment Day is uavoidable from T3.
2. John Conner will be the future leader o mankind.
3. Skynet will be built."

"In the future John is probably afraid of meeting people in a large area because of the chance another one of his friends is now a cloned Terminator. By meeting people one at a time with Cameron screening the person there is less chance of another infiltrator getting right to the president. "

"1)Possible, but I dont' believe that.

2)No, he was under drugs, and he saw the face of 2007 John in his memory. John is a scarred hard man in his 40s in T2 and therefore since the writers want to work on that continuity we have to assume he's that way."

"This cannot be true. Remember, in season one, episode 9 Derek explicitly states that he celebrated John's 30th birthday with him. "

"Trust, who can you really trust. for me the guys i work with, but for John Trusting metal or at least Cameron may be one of the only things he can trust. Computers will either be compliant or noncompliant so either work with John or kill him, Humans are unpredictable. They can use you for there own gain then screw you over "The Human Element" "

"I did not realize the had shown John in his 30's in the future. Still, young John could also be there in the future hiding out and helping the resistance."

"Just watched the scene you referred to. All Derek says is "Are you kidding, I celebrated your 30th with you." All it means is at some point in the future John is 30's year old and Derek celebrates it with him. Technically, since he was born in Feb of 1985, he would be normally celebrating his 30th on Feb 2015. But we already know for a fact he jumped forward 8 years which would make him really 30 on 2023, if he no longer move in time. So we know Derek celebrates his 30th, before he comes back, but which one."

"Yes, I do agree with you Will. I am fairly certain Riley is from the future. I am less sure about young John in the future, but the signs are definitely pointing that way. John and Cams relationship in the future that Jesse and Derek keep talking about, seems to involve some physical manifestation of love and would make more sense if John is still relatively young. Not some 30 year old guy nailing a cyborg built to look like a 17 year old."
