In Terminator: The Sarah Connor Chronicles, Season 2 Episode 2 Automatic for the People, in the beginning of the episode John has the below conversation with Cameron
(As per Terminator Wiki)
John: It's healing quickly. (Inspecting Cameron's wounds)
Cameron: Quicker than yours.
John: What about the rest of you? You're back to normal?
Cameron: Things have changed, John.
John: What things?
Cameron: You can't be trusted anymore.
John: Me? I can't be trusted anymore?
Cameron: You risked your life to fix me. That was a very dangerous thing to do. That could upset people.
John: They'll have to deal with it. (John looks pointedly at Sarah and Derek)
Near the end of the same episode, John & Cameron have the below conversation.
John: about what you said before, about not been able to trust me..,
John: I don’t have to prove anything to anyone, anyone, including you…!!
So my question is, what does John mean by saying that "I don’t have to prove anything to anyone!"
