Sometimes, he wonders exactly how much she knows. He wonders if she knows facts, like the birthplace of Nicholas Flameland Dumbledore's exact age and where the Mirror of Erised came from. He wonders if she knows how to fight, and how to defend herself, and that Ron didn't love her that night at the Yule Ball, because she didn't even love herself.
He wonders if she knows that the war will kill them, both of them, and she can't do a thing to stop it.

Padma doesn't even know that Harry would do anything to save her.
