Walden invites a depressed and lonely Alan to spend Christmas with he and his mother, Robin. Alan is clearly smitten when he meets Robin for the first time. We learn that Robin is a primatologist and has been working with gorillas since Walden was a baby. Walden reminisces about his childhood and recalls his imaginary friend, a gorilla named Magilla. Robin tells him that Magilla was real and he grew up with Walden until Magilla became too big to live with them. Walden storms out upset at the fact that he was a part of a science project and his brother was a gorilla. Alan tries to rescue an intoxicated Walden down from Zoey’s roof. Jake and Eldridge both lie to their parents on where they will be during the holidays.
