Among the things that they're 'browsing' through, Skellig finds a bigger bag than the tiny one he brought with him originally; the copper tins go into it, as well as some of the fine leather. (He has ideas for something to make with that, which he will contemplate in greater detail the next time they are back at the Lair with free time on their hands that is not being spent in bed.) He frowns slightly at the telling of the Captain whipping the other sailor, though he is not surprised.

"Even if it is not the brightest idea to try to thieve while you are stuck upon a ship at sea...that is still not right."

The door is locked; there is obviously no key to be found, but that does not matter when you have tricks up your sleeve. Skellig easily bypasses the mechanism with a few utterances, and then pushes the door open, stepping inside.
