[It's probably for the best that Lance is totally unaware that that's what Hux is thinking, because he already has enough trouble sleeping in this ridiculous place.

Instead, he's focused on trying to decide how much he should push arguing on the subject of likelihood of getting away with murder; it's not like he thinks he's going to change Hux's mind, so if he's going to argue he needs to have a different reason. Besides, it's probably for the best to keep it to himself just how familiar he is with investigating murders and criminals.

So again he decides only to address the last part of what Hux said, because discussing that could potentially lead to useful insight.]

It does, but when that's acceptable is highly specific and killing someone on your side is almost never one of those situations.
