Echoing my love for Bagoas/Illyria. And I think the same goes for her as well, that he acts the way she expects him to. So that initial wall is kind of taken down for her, because although he's "lower" than she is and he's oh-so-lucky to be allowed to converse with her (in her eyes, obviously), they are what they are and they act like it.

Also I'd love to see him befallen by some April Foolery, but I can't think of one particular thing. If I think of something I'll let you know! I'm sure whatever you go with will be hilarious. Poor Bagoas.
