Kathy says that she’ll drive her, while Beck and Walt follow behind them in the truck. Mim blames Kathy for wrecking her family, and she also insinuates that Kathy’s been hiding the letters from her mom. She shows Kathy the letter that says, “Think of what’s best for her [Mim]” (303), and from Kathy’s expression Mim realizes that she wrote it, not her mom. This means that it’s been Kathy, not her mom, looking out for Mim’s best interests. 

They arrive at Sunrise Mountain Rehabilitation Center, and Mim realizes that her mom isn’t physically sick; she’s been hospitalized for depression. Before Mim goes inside, Walt gives her a stick-figure drawing of her, Beck, and himself. This gesture makes her cry. Beck pulls her aside and asks why she didn’t tell him about Kathy being pregnant. He squeezes her hand for encouragement, and she knows that Beck and Walt “aren’t coming inside, because this isn’t for them. This is my wooden box” (311). 

Once inside, Mim vomits in the bathroom. She and Kathy walk down the hallway to Eve’s room.
