Robbie, Coulson and others in “Unfinished Business”

Robbie

If we're going to get my uncle, I'm going with you.

Coulson

No, you're not.

Mack

If your uncle can lead us to Lucy, then maybe we'll let you out to bust some ghosts, but until then, your ass stays on the plane.

Robbie

I don't take orders.

Coulson

Then this will be a new experience.

Robbie

You can't keep me here.

Coulson

Maybe not. But you take this plane down, you'll be burning up the only people in the world trying to help you.
