Savannah is dangerous, you can't stay in the city and be safe, so you're headed towards the ocean (and hopefully a boat).
Omid's leg is hurt, it seems like it's infected, and he's barely able to move.
Kenny wants to go and Christa agrees, suggesting Omid be carried.
Kenny is against that, saying you can't outrun walkers.
Christa isn't leaving without Omid because she's pregnant and loves him.
Kenny isn't wasting anymore time in a dangerous place and is leaving. He offers you one chance to join him or he's gone.
Do you leave Omid or stay behind and try to help him?
