Rachel claims it was a temporary bed swap or a trial. But as far as I can tell we only have her word for that. I can't find where it is verified anywhere.
I saw him discussing the situation with Dave and Mario, I think, a few days ago.They were trying to work out ways for him to keep it.
Ben was asking, "Should I say anything, or just stay in there, and wait until she asks for it back?"
They were telling him to just wait until she says something and then tell her you're staying put, basically.
Then Keeley left, Rachel moved back in, and his attempt to have more quiet has completely failed.
