Karl shows up with mint chocolate chip ice cream to cheer up Julie, after Susan told him she's been upset. She worries that her attacker is out there, since he knows where she lives and what she drives. She's afraid to go anywhere, since she could be followed. Karl suggests they switch cars, and she's surprised he's willing to drive her tiny car. He says as long as there's AC, he'd do anything for her and gives her a sweet kiss on the forehead.
MJ's ball rolls onto Katherine's lawn, and he sees her on the porch looking sad and asks if she's okay. She tells him life's complicated, but it's just grown-up stuff he wouldn't understand. He shrugs and turns to go, but crazy Katherine calls him back and shrugs herself -- "Since you asked..." Later, MJ's looking sad and thoughtful as Mike talks to him about parties and ponies. He realizes these childhood dream moments aren't getting through to MJ and asks if he's okay. MJ says he's worried about Mrs. Mayfair. "She's not getting any younger, and it's really hard to meet guys in this town." Mike laughs and asks where he heard that. He says Mrs. Mayfair told him, and she also said that Mommy stole him from her, which makes her a bad person. Mike tells MJ his mommy is a great person, and then storms angrily out of the house. He finds Katherine working in her garden and steps on her work. He asks if she actually told his 6-year-old son that his mother's a bad person. Katherine stands up and says she would have used more colorful language, but like Mike said, he's only six. Mike tells her she's never seen him angry, but if she wants to, she can just talk to MJ one more time. Then she'll know what he's capable of. Katherine tells Mike she loves MJ and would never do anything to hurt him, but Mike replies ominously, "One more time." I get that Katherine's a lunatic, but maybe if someone actually were nice to her instead of the whole block taking Susan's side, apparently, she might not be such a wreck. Someone, at the very least, least needs to get that woman into therapy, like, yesterday.
