But one could still make more of a case for at least Andy's survival, than all the Carley, Kenny, Lee threads of the same subject.
In episode 3 during the argument with Lilly and Kenny, in one of the lines of dialogue you can choose Lee comments that it could be worse, and that no one has been bitten for a long time. Then Ben yells "Do the St. johns count?". I think this means they were eaten alive by the walkers if they were not killed by the group, but indeed you never know...
