I plan on waiting until the very last minute to tell Padma and Seamus that as council members, their attendance will not be required (I'll tell them that Hydra's isn't, either, though we of course know that's not true). I was thinking just after the Prefect's meeting before everyone leaves for Hogsmeade.

I was thinking it may be a good idea to have you and Justin there when I tell them, just to be on the safe side.
