I know it's a pretty old rumor from last month, but if Lilly was left to die after the RV scene how far do you think they drove to reach the train? It was at least a night that passed. Also she would have to get there in time before the horde overtook everything. That brings something else. WAS the RV still there when the horde was coming through towards the end of Ep. 4? I have so many thoughts in my mind conflicting this theory, but what the heck.
