The episode begins with Sue writing her journal. She pens down the magic of Christmas and also mentions about the movie “Love Actually” which is often shown on cable. Next, in the hallway we see that Artie has hurt himself and Finn asks him what happened. He tells Finn that his wheel chair has no chain and so he fell backwards and hurt himself. Finn takes him to the nurse’s office and she goes to call Artie’s mother. Artie tells Finn that he is tired of feeling helpless every time and that this time few girls had to help him back on the chair. Finn puts Artie to bed, and Artie immediately dozes off wishing that he weren’t tied to that dumb chair.
Next we see that Artie is dreaming. He is in the hospital and his legs are perfectly fine. He goes to tell Tina about it and finds that she is stuttering. She wonders what Artie is trying to tell her as there was nothing wrong with him in the first place! Just then Rory arrives and he is his guardian Angel for Christmas and he has made Artie’s wish come true; Artie has never been in that horrible accident and he isn’t tied to that dumb chair.

Kurt doesn’t know who Blaine is. Will is busy drinking and there is no Glee club. Rachael is working as a librarian and she sings in the chorus. Artie runs to Rory to know what is happening and why are things so messed up. Rory tells him that Artie on the chair was the one who always kept the club together; he was the glue. As there is no glue now, there isn’t’ a Glee. Artie decides to bring everyone back together. He sings ‘Feliz Navidad’ and the rest look at him as if he were crazy. At the end of the song, Finn exclaims that it was so gay! In the hallway, Artie sees an empty wheelchair and asks Rory if it is his. He tells Artie that it is Quinn’s and after the accident she died of a broken heart as her spirit never recovered; just like her body never did. In NY, Rachael is about to leave for a cruise.

There is a little friction in the beginning between the women, but then they all agree on the fact that Puck ran out on all of them and that he was an ass who did just one thing right; bring them all together. At school, Brittany is handing over expensive gifts to her friends as she believes that the Mayan apocalypse is about to come on December 21 and that the world is going to end. Sam believes in it too. They decide to tell the club members the way they feel about them; but the group thinks that Sam and Brittany are trying to insult them and they leave.
