He bought Harry a hamburger and they sat down on plastic seats to eat them. Harry kept looking around. Everything looked so strange, somehow.
"You all right, Harry? Yer very quiet," said Hagrid.
Harry wasn't sure he could explain. He'd just had the best birthday of his life –– and yet –– he chewed his hamburger, trying to find the words."Everyone thinks I'm special," he said at last. "All those people in the Leaky Cauldron, Profes-sor Quirrell, Mr. Ollivander... but I don't know anything about magic at all. How can they expect great things? I'm famous and I can't even remember what (1) I'm famous for. I don't know what happened when Vol-, sorry –– I mean, the night my parents died (2)."
(Harry Potter and the Sorcerer's Stone)
I guess what (1) is a complementizer that moved forth from for's complement. And it’s the pronoun referring to what happened the night my parents died (2), or short form of this. Is this a proper parsing?
