Sue reflects on the holiday season, imagining it as a setting for a series of plot lines sandwiched between commercials breaks, much like the movie "Love, Actually" - "which is a movie that I don't think anyone cares for but is constantly on cable."
After an angry, humiliated Artie slips on the ice and cuts his face, Finn helps him to the nurse's office, where he stews about being helpless and pitied and wishes he never had to be in the wheelchair. As he tries to rest, he slips into a fantasy in which his legs are completely mobile. Surprised, he tests his legs and walks around McKinley, quickly realizing that reality has changed when no one is surprised at his mobility.
After Artie realizes that Tina still has her old stutter, a guardian angel appears to him in the form of foreign exchange student Rory, who grants Artie's wish that his accident had never happened. However, this means that he never joined glee club, so some resultant changes - like Tina getting over her stutter, and Becky learning self-respect - have never happened, either. Finn and Puck are both bullies, terrorizing Kurt, who's been avoiding school and has yet to graduate and has never met Blaine; Will never started the glee club and lives in an alcoholic haze, still married to Terri, while Emma actually married Coach Tanaka; Rachel is still in Lima working as a librarian, never pursuing dreams of stardom. Rory reveals to Artie that, without his accident, he'd focused on football and never became the glue that held the glee club together.
Artie tries to set things right, assembling his friends to convince them they should be in glee club together, offering a performance of Jose Feliciano's "Feliz Navidad" as an example - but Finn deems it "so gay." Artie learns that Quinn never got out of her own wheelchair without his support and ultimately died of a broken heart. The shock brings Artie back to reality, where his mother has come to pick him up, and this time he graciously accepts Finn's help back into the chair, realizing that it's part of who he is and how he's affected his friends.
