Could just keep moving, open a spot and if he asks again tell him it is up to him to keep up. He's never been a heavy player in the rp. Even if he stayed I wouldn't consider him a spot taken.
No I understand and no apologies, we've talked about mine in the other. It's cool. I love horrids character but I completely get what you are saying. I was always taught R.P. means Read, then Post. If you're not gonna read, why rp?
