I think they've pretty much have Daryl as Lydia's father figure at the moment. I'm guessing when Michonne leaves Negan'll be the same for Judith and possibly Rick Jr.
Kind of curious about the CRM group after seeing that FEAR episode. The armor does seem to slightly hint that they're the TV equivalent of the Commonwealth.
Wonder if they'll save that for the Rick movie (Curious how that's going; El Camino pretty much popped up nearly complete out of nowhere, so I'm wondering if they're filming it now) or deal with it in the show with Eugene's radio.
Still think it's possible that they're the people who created the Walker virus in the first place.
