I don't think Hope is dead. I know it doesn't really help the suspension of disbelief, but killing the blind girl who's mother was tortured by Zombies at this point just doesn't make sense. If anything, I think maybe the shooter was someone closer to her that shot and wounded her to avoid suspicion.

The shooter was also using the silenced pistol that was missing from Burt's bag. So who had access to the bag between the time they packed everything and the time they left? Wasn't Saul's Mom messing with the bag when she was packing the medicine for him?

Also, where did you all pick up on another traitor? I thought it was the land-lord. Wasn't he the one who stole weapons, ammo, food and notified the maulers over the radio? Did I miss something where they figured out he wasn't really the traitor, or that there was another one?
