Joker has made the mistake of being very pretty which, as it turns out, is something vampires appreciate in their own. Sure, becoming a vampire makes you a super hottie anyway, but a headstart is always appreciated.

....So yeah he was vamped.

As a nice trophy and probable tribute to giving RM the middle finger, he's been put in a very pretty literal bird cage. Needless to say he's not going to be happy about it... but thanks to his sire's influence, he's not particularly inclined to leave it, either.

And frankly.... he's gotten to be pretty hungry as well.

Good luck with that.
