@MingMing: If he told her not to resist a spell and that it wouldn't hurt her would she let him cast it on her? I'm thinking of having him try to cast mindlink on her so that they can talk freely without having to worry about being over heard by the guards outside of the room. She could try a sense motive but he's not trying to hide his motive about this so all she'd get is that he wants to talk to her without being overheard. And the the 'spell' won't hurt her.
