I'm comment stalking again, but that's so much how I felt about Snape and Draco. That's such a tricky pair with me, because if there's any hint of anything even remotely romantic/sexual between the two of them outside a carefully-drawn Drapery context, the squick factor is on par with character death for me - any of that, and it feels to me like Draco is stealing what's rightfully Harry's. But here, Draco is so obviously and beautifully in love with his wife, and he's got such a wonderful rapport with Snape, AND he's so clearly admiring - however belatedly - of Harry that it just works.
