Question: As Banner is transforming into the Hulk and Romanoff is pinned, she says, "I swear on my life I will get you out of this..." But rather than comfort Banner, it seems that this promise is finally what sends him over the edge, prompting him to snarl the question, "Your life?" Why would Romanoff's promise affect him so much? Or am I simply over-analyzing?
Answer: He is upset that he may indeed kill her while she is trying to help him and angry with her that she doesn't intend to just run away to safety.






Answer: It is not Romanoff's promise that sets him off. Banner is already too far gone from the attack to be comforted.
