While they're all busy worrying about the amazing bendy twins escaping their bonds, Lydia finishes going through the chest, shaking out the bit of cloth she found inside to see if it would be of any use to anyone.  The naked portraits and the chest get to stay right where they are, as she heads for the wall safe once she's checked out the bit of cloth.  For the moment, she lets the others deal with the chef and his barrels of pickled elf ears, or whatever the hell he might have in there.  She wants to see what is going on with the hidden safe, and how difficult it might be to crack that baby open and see what's inside.
