You're making a bigger stink about him just being here at the moment than he even warrants with his actions.
If you're going to complain about him right now, atleast give him the chance to do something worth complaining about.
If you're that focussed on him just being back then you're only going to try and provoke him to make mistakes and then blow them out of proportion.
We'd have all noticed he was back in due time, without the help of a topic.
