I can't shake the feeling that Rick is going to die. When Daryl sided with Tyrese, it made me think of the scene at the church a few episodes back where Rick basically told Carl that they can't trust humanity anymore. Carl disagreed, saying that they can't give up on people. Add to that how Michonne tried to take Rick's place on the mission, it just seems like they are setting it up for things to go on without Rick. Hope I'm wrong.
