I’m not fan fan of his mom (or Mary for that matter), but I wonder if Brandon is low key getting back at his mom right now. He kept mentioning he didn’t want her to relapse during this visit. But I think the stress and pranks he’s doing will cause one. It’s not nice to cook her frogs as a prank and telling her after the fact. Also clearly she’s terrified of spiders. And seeing that ginormous spider on the wall freaked her out. I’m not a fan of his mom and she did some major damage to him growing up. But these two things, plus the animosity with Mary will definitely cause her to relapse.
