Reese decides to sunbathe in the backyard of the Wilkerson house without putting on sunscreen. Soon enough, he's terribly sunburned while he was napping.
Later on inside the Wilkerson kitchen, Reese attempts to peel off the burned skin by starting with his right foot. However, Lois catches him in the act and warns against it because he risks getting leprosy if he attempts it. Reese is forced not to peel his skin while his family along with Stevie and Abe Kenarban are celebrating Dewey's birthday. Lois apologizes to him about the birthdays being less than what he deserves because of the debt they have to pay off with Hal's trial and the other taxes.

Reese comes in the room excited that underneath his old skin, there's a new skin underneath it that he makes his own snake skin suit.
In the Wilkerson kitchen, Hal and Lois bid Abe and Stevie good night and were just preparing to go to bed themselves until Kitty shows up at their door unannounced. She tells them that while she was away doing what she always wanted to do, she regretted leaving Abe and Stevie and asks for their forgiveness. Hal is more than willing to forgive her because he knows that she just made a mistake. However, Lois puts her foot down and tells Kitty off that she'll never forgive her for what she's done.

In the boys' room, Malcolm is helping Stevie with his recording when Lois offers him some lemonade. He refuses her lemonade and tells her that he'll be drinking juice from his mother's choice. It is apparent that Malcolm is torn between the two choice he has, defending Lois' thoughts about Kitty and forgiving his friend's mother. If he sides with his mother, then he'll lose his closest friend at school. However if he forgives Kitty, then Lois will make his life a living hell. Still when he argues his case with Stevie, Reese rudely interrupts them and tells them about his plans to make his own snake skin suit.
