Tony Stark: Romanoff. You and Banner better not be playing "hide the zucchini."
Natasha Romanoff: Relax, shellhead. Not all of us can fly. What's the drill?
Tony Stark: This is the drill. If Ultron gets a hand on the core, we lose.

Tony Stark: Well, like the old man said... (looks at Steve) together.
