(Tony has another panic attack...)

Tony Stark: God, what am I gonna do?

Harley Keener: Just breathe. Really, just breathe. You're a mechanic, right?

Tony Stark: Right.

Harley Keener: You said so.

Tony Stark: Yes, I did.

Harley Keener: Why don't you just build something?

Tony Stark (calms down): Ok. Thanks, kid.
