This thread is about TSCC BIG FINAL PART2 video.
Cameron sent the mallware to almost knaker John Henry. (When she logged into WWW, via the traffic lights) She had sent a command to John Henry to go back in time. He was about to activate the time machine when tech head stopped him.
Cameron gave him her chip because she was too badly damaged to travel through time machine, METAL exposed. John Henry either swallowed the chip or cut himself open and put the chip inside him. Terminators (Metal) can only time travel if completely covered in organic matter.
Cameron was really after John Henry and not John Conner. He is the one whom reprograms robots and brings skynet to its knees.
