I've never seen this pairing before! I can't help but imagine them bickering away during an awkward Sunday lunch at The Burrow, missing each other's points and talking in riddles.

I loved the weather terminology dotted throughout the fic – it was a very Percy-like pedantry and it made me smile.

The following parts were my favourites:

"I simply do not trust anyone else with the task of picking these mushrooms."

Classic Snape. Very in-character.

Percy’s lips compressed as he stood and stared at Severus, trying to work out a way to say I care about you too much to allow you to risk your life for a fucking mushroom without getting himself mocked for the rest of his natural life.

This is just hilarious. Percy's so delightfully neurotic and this exchange captures their strange, nuanced relationship wonderfully.
