What if Clementine/Christa judge Luke or Kenny
Now a majority of the people here seem to think/know that we'll have to choose either Kenny/Luke over the other, or neither of them, and that seems like it could definitely be a possibility. What would be interesting about the choice is if you were forced into a situation where you needed to leave the person you chose to save for a little while, in order to search for food/resources more efficiently, and ended up reuniting with Christa on the way.
You tell Christa about your experiences after you were separated from her, and then you get to the part where you were forced to protect one person over another in a matter of seconds. You then tell her about a choice they made concerning the baby, that lead to something horrible (Kenny wanting to ensure the baby's warmth/health kills an innocent man in cold blood for his resources at one point, or Luke leaves Clementine behind at one point to save the baby from the remaining Russian bandits) and how that decision only left them with more consequences, for instance, the innocent man's group robs them and steals the baby, believing Kenny to be a bandit who uses an infant to lower people's guard/Luke leaves the baby somewhere hidden and rushes back for Clementine and when they get back to location the baby is gone. This leaves your Clementine with resentment towards the person they saved, Christa picks up on it and asks if Clem even thinks the person they saved was worth saving in the first place.
You then get question from Christa about Luke, or Kenny:
Do you still trust him?
Did you only stay with him because he was all you had left?
Do you think he had to do what he did?
Do you forgive him?
Do you think it would be a good idea to go look for him, and travel as a trio?
At the end of it your Clementine has four different ways to end this conversation and the episode:
You told Christa about Luke/Kenny, forgave him, and went back for him. (Humanity)
You told Christa about Luke/Kenny, forgave him, but left him. (Empathy)
You told Christa about Luke/Kenny, didn't forgive him, but you still went back for him. (Empathy)
You told Christa about Luke/Kenny, didn't forgive him, and left him. (Survival)
