Can provide! Five is always the easiest person to run into, he can just "appear" for no reason other than he's too lazy to walk somewhere or open a door. Maybe he wants to check out the same bookshelf she was eying and beats her to it?? Or maybe he's gone to spy in the exact spot she had already picked out, whatever works.

What does he care who sees him? He'll just disappear again, this never causes any problems.
