Omid and Christa: They will come with you if you show the bite to the group OR if you help Omid get on the train first in Episode 3 and don't bring Clementine to Crawford. Kenny: w/o conviction: If you side with Kenny most of the time during the whole game before this scene, he will come with you. w/ conviction: If you do not side with Kenny enough, he will reject coming and you will need to either give him a good reason why he should come with you, or let him stay. If you look after and protect Katjaa and Duck, and say that Clementine is your family, he will be convinced enough and will come with you. Ben: He will join if you vote for him to stay in the group back in Crawford, or say that Clementine stood up for him.
