Setting Brad up in a tent in the garden would be a better solution than forcing him to room with George. It's just needless drama, and George is a butthead. And Brad needs to learn to stand his ground -- I hated how quickly he changed his tune when it looked like he might be able to get out of painting.
I really hope the wedding delay doesn't cause any problems between now and when it gets resolved, but I expect it will. The writers don't drop things like that in for nothing (except when they do. In that case, it'll be a throwaway bit of condition in 5 years about the date of their anniversary.)
