[Jack has escaped the brig and located the chest, gaurded by Mullroy and Murtogg]

Halt there, or we'll shoot! [He and Murtogg point mini-cannons at Jack, but are visibly shaken by blast from the outer fight]

[Pauses, then smiles]

Good one. Just come to get my effects! [looks around at the two] ... Admirable though it may be, why are you here when you could be elsewhere?

Somebody has to stay and guard the chest. [points the cannon back at the chest]

[as Jack is taking his effects]

There's no question, there's been a breakdown in military discipline aboard this vessel.

I blame the fish-people.

[Sarcastically]

Oh, so fish-people, by dint of being fish-people, automatically aren't as disciplined as non-fish people?

[as Jack is taking the chest, which neither seem to notice]

Seems contributory, is all I'm suggesting.

It is true, if there were no fish-people, there'd be no need to guard the chest.

And if there were no chest, we wouldn't need to be here to guard it.
[both realize that the chest is gone, and the apparent danger they're in]
