We can definitely have a kidnapping. It would involve a conversation with THAT WOMAN HE DOESN'T TALK ABOUT, and it would probably end with him geassing Anya unless we can think of some way where Anya wouldn't wake up and be all "...he kidnapped me..." and then tell everyone how terrible he is.
He would rather not resort to kidnapping, so if he can extract her word to stfu when he makes his post, he will probably avoid that route entirely.
