Obi-Wan: Poison gas? I hold my breath.
Qui-Gon: Me too. I look for an exit.

Qui-Gon: Right, I'm gonna kill the butler robot.
GM: No, you can't see it.
Qui-Gon: I swing my sword where it was just standing.
GM: Very well. You miss.
Obi-Wan: This is getting us nowhere.
Qui-Gon: We should get our ship to blast us free.
Obi-Wan: You mean our ship that almost certainly just exploded?
Qui-Gon: Is that what it was? Okay, let's take over this ship.
GM: Are you still holding your breaths?
Both: Of course!
