It isn't that he fancies Granger. No, it's more that she...puzzles him. She's quite bland, not changing much since their days at Hogwarts, her hair still wild and bushy and she still carries herself in the "I'm-smarter-than-you" fashion. But she has certainly matured, filling out in all the right places that sometimes when he was alone, he pictures her lips parting in an "o" of pleasure.
