There are a lot of threads on here with theories that discuss Clem reacting, snapping, loosing her sanity and humanity, etc. I saw this play-through on YouTube where Clem slaps and punches Walter for allowing Nick to die. The scene is at 14:18.
After reading theories on here and replaying the scene, it kind of surprised me that Clem reacted like this considering that she only met Nick about a week ago (in the game's universe). How do you think Clem would react to the death/murder of any of the other remaining group members? What do you think will make Clementine react like this again? What event do you think will send Clementine over the edge?
