Chris calls to Mack to guide Tina back. Mack leads Tina to the source of Chris's voice, but they still cannot find the entrance. Despite Bill's warnings, Chris reaches into the portal and falls into the fourth dimension, an abstract, crystalline landscape which seems distorted, and constantly turning upside down and sideways. Bill advises him not to move. Chris sees Tina and Mack and calls them towards him. Bill calls for him to hurry. When Tina and Mack close in on Chris, Bill grabs them and pulls them back into the bedroom. Ruth rushes Tina to another room.
