"There's a shop two streets over. The storage room is secure." One of the places he does business with and has access to the back for picking up and dropping off goods. It's Society; their movements won't be recorded, but he's already pulling an illusion over all three of them so anyone looking won't notice more than normal people having a normal walk, their faces and clothes too regular to remember.

He isn't sure about wings, but he can pull some of the pain, at least. It takes more focus, moving and trying to take a piece of the wound and not the wound itself, but he'll start syphoning bits of Jay's discomfort to people they pass. It's not much, but it should give him a little bit of relief. For the rest -- Balthier will need a minute to think and a lot more concentration.
