I would have thought it would hinge in how many duties/engagements that K&W would have to do... Presumably it's going to jump right up now H has buggered off, and will again when E pops her clogs.
But then , maybe they'll just be day kids and crack on with it. It's not like there's centuries of tradition. Going to school was only a recent thing. It was "groundbreaking" when W went to school when he was a wee lad.
So... we'll have to all wait and see.
