I don't recall seeing the guy who had been killed by Rick with the "marauder" group when they found Daryl, but I'm not 100% sure. The only two guys I recognized for sure were the older leader and bandana guy. I'm hoping they don't jumble up the timeline by having Daryl meeting the "marauders" before Rick's stay in that house. The show is already hard enough to keep track of with the main cast split into small groups.
I've been thinking about this and I'm not sure what the timeline jumbling would do at this point for the season. It would have been a "oh crap" moment if at the end of Rick's episode that the whole Maurader gang was revealed and Darryl was with them. However, at this point, I don't think it serves any benefit/shock value.
