Headcanon that of fucking course Mcgonagall was invited to Ron and Hermione’s wedding and that during the reception Ron approached her at her table and held out his hand and asked her to dance, “you know, for old times’ sake.”
They’d done the first dance as a couple and the dance with his mum. He’d danced with Ginny and a rather tipsy Harry who couldn’t stop saying, “I love you, man. WE ARE BROTHERS!” No matter how many times Ron agreed that they’d been brothers for more than a decade, Harry just shook his head and grinned until Ginny took him off for water and possibly a sobering charm. But there was one more person he had to dance with. She hadn’t danced at all this evening and it wasn’t right.
He wove through crowd, nearly losing an eye to Scamander and Luna who were imitating some creature they’d found in the wilds of the Yukon. He found Minverva McGonagall, seated next to Hagrid. She was wearing plain black robes, but near the collar she’d pinned a small brooch shaped like a phoenix.
“What is it, Weasley?” She inspected his outstretched hand.
“May I have this dance, professor?” He asked solemnly because she’d say no if she thought he was poking fun.
