Ren tells his grandfather that he wants to take his piano with him. He says that now that he's living with him, he'll be able to play the piano again. But he can't play it because of a sticky touch on the keyboard. Ren asks his grandfather if he still has the right to touch the piano. His grandfather says that his parents were killed for their part in the h-virus outbreak. Ren says that living in peace doesn't mean anything to him, and that's why he has to go to Regan's house and kill her.
