- “Tony? You're being uncharacteristically non-hyperverbal”
Natasha introduces herself to Tony as Natalie Rushman, supposed legal assistant and Tony immediately tries to impress her, which Pepper picks up on and is jealous of, as Tony insists he make 'Natalie' his new assistant. After Tony's crisis he is told by Fury and Natasha that she is really an agent with S.H.I.E.L.D. and Tony's even more impressed with Natasha. Their interactions are dripping sexual chemistry, and while Tony seems well-aware and attracted to her, he never acts on it.
- Tony – Focus up, I'm sorry, did I just mishear you or did you agree with me?
- Natasha – Oh, I wanna take it back
- Tony – Who is she?
- Pepper – She is from legal and she is potentially a very expensive sexual harassment lawsuit if you keep ogling her like that
- ―Enter Natasha
- In her report on Tony i.e. the 'Avengers Project', Natasha writes "Mr. Stark displays compulsive behaviour... prone to self-destructive tendencies. Textbook narcissism."
