Excellent! You are forgiven.
in the movie novelization of T2 john connor himself was the one that sent the t-800 after they finally took out skynet and seen it sent the t-1k but they didn’t know what it was so they sent a hacked t-800
and wasn’t John’s dad kyle reese ? who went back in time to make sure the original t-800 didn’t kill sarah because they found out about it?
