Uhhh,
"You were going to kill that guy."
"Of course I'm a Terminator.
Thats one exchange in T2 I've never liked. "Of course, I'm a Terminator" just doesn't seem to me like the kind of thing a Terminator should say. I would have preferred that he responded to John with silence or a simple 'yes' there.
That line was a bit too "inform the audience" for me.
