"If it's a spell you're worried about, I can easily identify and dispel it. Of course, we'd have to be somewhere a bit more private." As they're still in the middle of the friggen library, of course. Strange adores showing off and he loves being the most important man in the room but like hell he's going to cast magic in the middle of a crowded place.

He also might not be able to identify or dispel said spell in the first place but he's conveniently ignoring that part as he talks to Joker! He'll fight that battle if he gets there.

At the question about the mages, however, Strange purses his lips, frowning as if he's just tasted something sour. It's a bit of a sticking point, the fact that the council's here and in his way and bothering him so much. Strange'll be a bit more difficult but it's obvious that whatever the mages are doing is pissing him off something fierce. "You're the psychic, shouldn't you know that much already?"
