Your theories for Episode 4 and 5?
These are the images of the select screens.
In Episode 4, I feel that Clementine will be mindfucked by the loss of her comrades. I expect everyone close to her to have died already. Carver lives.
Episode 5, she runs away from Carver to Wellington alone where she is left in a helpless state. She eventually finds a way to hide from him and stay out of his reach. She has run so much that she is now left in a place where there is no one left. Carver continues on with his life while Clementine is trapped in Wellington waiting to die.
I don't want this to happen, but the darkness of it all makes me think so. If you search the music for the select screens, it used to be pretty eerie and creepy. I'll link it.
