You think you can do that?

Hi. Is You think you can do that? natural in the dialog below? And is it phrased the best possible way (without including "do" at the start) to be slightly condenscending? Thank you.

A woman is yelling at her boyfriend over something. When she finally stops, he says -

Boyfriend: Can we watch a movie now?

Woman: Sure. I'll try to be quiet then.

Boyfriend: You think you can do that?

Woman: Yeah.
