Lilly got left behind at the Motor Inn? That would prevent the death of Carley/Doug.
If only Kenny pressed on that gas pedal a little earlier...
Carley/Doug probably would've died later on, or would've been left behind with Omid and Christa. That would've put Clem in a more stable position in Season 2.
Would have been left behind with Christa and Omid???? What are you talking about?
Y'know, in Episode 5 when Lee goes down to fight the herd. Christa and Omid are left on the roof of that building.
