From this passage in the Harry Potter series:
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.
Does "yet" mean "still" or "in spite what has been said"?
