Excellent scene there. DD is really up against it, as he needs to decide who he wants at Hogwarts more. He may try to make Harry compromise, but from Harry's perspective why should he? And what does DD have to offset what he wants from Harry? Harry can get a much better education from the people he already knows with no downside. DD will need to make some promises about Snape's behavior that Snape won't keep, and Harry will be gone. Or worse, DD will try to use force and bring everything crashing down around his own head.
