Terminator 3: Rise Of The Machines Discussion

[Vash]

If I'm not mistaken, I think John Connor in T3 was talking about the events of T2 while they were in the trailer park. He noted that the events of T2 happened the day after he met Katie and that if those events had not occurred, he would have married Katie and become acquainted with her father.

What I'm trying to say is that if the events of T2 did not occur, yes John would have been with Katie (and her father) much sooner, but John would not have known about the significance of Katie's father because he would not know about Skynet and other important details about Judgement Day (although he would have had brief knowledge of Earth's grim future since Sarah Connor probably informed him of her experiences from T1).
