Wesley is sitting at one of the tables near the bar, frowning as he struggles with a book.
It's not physically attacking him (given the books Wesley tends to read, anything is possible), but he seems to be attacking it.
Actually, on closer examination, he seems to be trying to repair it. He's holding a
bone folder in one hand and wrestling one of the book's bindings into position with the other. There seems to be quite a lot of glue--or rather wheat paste--slopped around the table, though.
This could take a while.
