I rewatched an episode of season 1 for background noise and it’s hard to believe Tammy wasn’t always such a bitch. Maybe it was just for the cameras, but when her family would confront her about weight she’d actually be receptive even if only a tiny bit and still they’d argue, it wasn’t a complete shutdown like she does now. She’d talk about weight loss way more. Seems as though she gave up in season 2 and became fully retarded in season 3. Don’t get me wrong, she was already pretty retarded, but there was signs of intelligence even in season 2. Now there’s nothing.
