Earlier in the part 1 of Season 3, Governor wanted to help Merle find Daryl. Now back to Episode 8 and 9, Merle has be labeled a terriost with his own brother Daryl, and earlier this season The Governor wanted Daryl has the inside man for the prison, now with Merle also in the "prison group" or about too. Merle will become that inside man. Where Daryl will be planned into the mix without knowing what's up, and I also believe that Merle will become the "Sucide King".

So Daryl will want Rick to let Merle in the gorup, and Merle will pled to him, and Rick will take him back but Glenn and Michonne will disagree with him, and question his leadership.
