If someone or something is killing people on board this ship, I would like to catch them, and stop them.

[ Where he's from, that would be the Captain's responsibility, so he wouldn't have expected anyone from outside to come in. He's just told Tali not to judge this organisation by her standards, though, so he's not going to judge it by his own in the next breath. ]

That's my priority, and until I'm told differently, that's what I'll be acting on.

Regardless of how they would do it - in what organisation, did you say?
