I was so surprised when the two died. Is so bittersweet that when she thought she was about to die, she thought about her parents ''My mom and dad are gonna be so pitiful. I'm sorry, what should I do...'' I don't know these lines made me want to cry a bit.
On another note, yes he is a fucking jerk, but he is an orphan, and the last person that he ever considered family just died. Everyone has their own way of dealing with grief, and although a very asshole-like one, we should cut him some slack. He was now completely alone.
