She doesn’t seem like someone I’d enjoy being around, but uncontrollable rage? She let out a loud scream of frustration when he was going out of his way to belittle her. To me uncontrollable rage would be her physically attacking him, or ripping a bunch of things off of his car, or slamming a cake into his face because she was mad, and yes I’m deliberately pointing out Angela’s behavior here. It wasn’t a great look for Kim, but it also felt understandable that she was fed up with him at that point. Walking away and screaming into a pillow would have been a better approach, but he also just runs away if she isn’t actively trying to get him involved in a conversation. She wasn’t violent, in spite of the number of comments on this one talking about how many people wanted to reach through the tv and smack TJ during that scene, and she only screamed and it wasn’t even at him because she looked up and let out the scream. That doesn’t feel like someone who is out of control at all, that felt like letting off steam to avoid losing her temper and trying to continue the conversation without descending into insults and personal attacks. She threw out a well deserved mama’s boy kind of insult when he went running to his mommy to complain, I mean come on if you’re old enough to get married you’re old enough to have a disagreement without involving your mother in it. Running away yelling for his mommy was by far the more immature response out of the two of them.
