The cross in the back of the car immoderately made me think it could be Gabriel, But that could go either way, I also thought the group that Rick and Daryl encountered could have been the Hunters (later to be revealed as cannibals) If that is the case they are not following close to the comics hunters (names and no woman) Maybe we will know soon but with the way things are going probably in 2 or 3 weeks when we see Daryl and Beth again, I can only assume next weeks will be Rick, Carl, Michonne, Tyreese ect.
