A series of Gallavich scenes told from Mickey's POV. Both from the show, and scenes filling in the gaps. I've gone beyond the point of Mickey fleeing to Mexico. As per series canon Ian does ditch him at the border, but don't worry. Everything comes up Gallavich eventually.

He can't leave the room. Her room. And it's all the Order's fault. Confined to a small space with only the Mudblood for company, something's going to give. Maybe his sanity. Maybe not. "There," she spat. "Now your Blood's filthy too!" DM/HG. PostHBP.
