Oh, it happens before. But we can't have a wedding if the family are in mourning, only I guess we don't technically have to mourn. It's not as if Draco were part of the family.

But if there's a national mourning or something, then we'd postpone. I dunno. It's really up to Pavs.

And whether or not he died a hero or something else. Though Harry certainly defended him and I agree, it's hard to imagine he could have been actually treasonous. If anything I think it was just that Granger tempted him, like the stories said, and he had a lapse of judgement.
