yeah, but that's why he has to go with him, otherwise he'd just tell rick (or glen) to kill him outright. his being his brother is the only thing keeping merel alive, but daryl knows he can't let him get into the prison, or have a reason to go in, so he has to ensure he stays away, by going with him.
It does make sense, I can see Merle trying to "infiltrate" Rick's group, Although I don't know how good his relationship with Woodsbury and the Governor still is (Unless they planned the entire thing..)
We saw on previews though that Andrea comes back to the prison, as a infiltrator of sorts? Then we see her with a knife and the sleeping governor (red herring that maybe she turns on him?)
(Im pretty sure I saw Andrea come to the prison in preview)
