Okay, I must have missed something... (spoilers)
I get that Alex used the car accident as the explanation for his disfigurement... but then, how DID he become disfigured?? Did his daughter attack him (hence his "f-ing b-tch" remark in the car)? If so, how the hell was she able to do so much damage? Did she knock him out and then go to work on him?
Sorry if I'm asking a dumb question.
