Sarah Connor is in a mental institution and John Connor is a juvenile delinquent.
The T-800 is sent back in time to protect John Connor, by John Connor’s future self, from the new model terminator the T-1000
The motorcycle truck chase in the drain where John is nearly killed.
John refuses to follow the T-800 instructions and instead insists they rescue his mother Sarah from the mental institution first. T-800 doesn’t want to do this because he thinks it’s a risky move.
Sarah has been John’s mentor all his life preparing him for when he must lead humanity in the fight against the machines.
Rescuing Sarah from the mental institution
They go on the run with the T-800 and begin teaching him to be more human
I don’t think either of these stages are used although you could look at the relationship between T-800 and John.
Sarah decides to leave John and let the T-800 be his father. In an insane world this is the sanest choice.
Sarah can’t kill Dyson when she is face to face with him, when John arrives he sees the humanity in his mother and instead of seeing her as a psychopath that he described her as at the start of the story, he now tells her he’s always loved her. He sees her as a mother.
The T-800 cuts the flesh off his arm as proof that he is from the future and then tells Dyson the story of everything he is about to do which results in the deaths of three billion people. It’s imparting God-like knowledge of the future.
They destroy Cyberdine, all the tech and Miles Dyson is killed. Ending any chance of Skynet coming to be.
The T-1000 chases after them and the final battle in the metal factory.
The T-1000 recovers from the shot gun blasts but T-800 appears with a missile launcher which strikes him in the chest and he falls into the molten hot metal.
John must say goodbye to the T-800 and live his life without him. At first he refuses but ultimately accepts it. This stage more or less is blended with the next stage.
T-800 can’t self terminate and asks Sarah to do it for him. He now knows why John cries but he can never do it himself. The best way for him to protect John is to die.
The future is saved and filled with hope “If a machine can learn the value of human life, so can we.”
Terminator 2; Judgement day takes on the challenge of being a sequel by introducing new characters and giving the old characters that we knew from the first film new goals and challenges rather than just repeating the same story from the first film like many, many, many other cash-in sequels do.
Meeting with the Goddess and Woman as Temptress missing? There was a cut scene when they pulled the chip out of T-800’s head and Sarah wanted to destroy it and kill him but John refused to let her do this. This could serve as the Temptress moment and John could serve as the Goddess for the T-800 as he inspires him to be a hero. That’s my best guess but feel free to include your thought below.
