Draco to help Harry reform Slytherin House. And Harry to take as an enemy whoever Harry believed, in his best judgment as a rationalist, to have killed Narcissa Malfoy. If Narcissa had never gotten her own hands dirty, if indeed she’d been burned alive, if the killer hadn’t been tricked—those were all the conditions Harry could remember making. He probably should’ve written it down, or better yet, never made a promise requiring that many caveats in the first place.
There were plausible outs, for the sort of person who’d take an out. Dumbledore hadn’t actually confessed. He hadn’t come right out and said he’d done it. There were plausible reasons for an actually-guilty Dumbledore to behave that way. But it was also what you’d expect to see, if someone else had burned Narcissa, and Dumbledore had taken credit.
Harry overlooks the huge out that Draco is leaving Hogwarts and so won’t be reforming the Slytherins.
