If we don’t get Percy Weasley shouting about how he’s junior assistant to something (I forget what he got to before he left after book 7) somewhere, even in s side Easter Egg, I will never be satisfied.
That is, of course, assuming the MoM would be taking place before the end of the Second Wizarding War. They could practically carbon copy the premise of Gringotts (a tour, with the trio wrecking havoc in the background), but I have a feeling that would feel stale.
We could always have Jamie Parker (adult Harry in the stage play) reprise that role as old Harry...doing paperwork. :sleep:
