Following the Professor's death by Abigail, Percier and Marty head back to Earth for Christmas. Marty wonders what they are doing, so Percier explains to him how Christmas works and wishes for the Professor's resurrection. Marty then notices that Percier is wishing for a "dirty" thought (being his lover), which she defends. The pair then hear rumbling in the distance and check it out.
Elsewhere, Chloe and Teleko are in a wooded area, the latter having strayed near a Rebel base. Teleko is looking for the "Christmas Spirit's resting tree", after having been explained about the concepts of Christmas based on Odette's view. Since she has no idea what the tree looks like, she simply takes all the trees in the area for Odette. Chloe attacks her, prompting Teleko to defend herself. Marty is terrified of the Invader and Percier states that they'll take them both on before they ruin their wish.
Teleko uses her powers to destroy Chloe's machine before departing. Percier and Marty arrive too late and the trees are gone, having been ripped from their roots. Percier laments about never seeing the Professor again. Marty recalls the Professor's phase "Researchers never give up", bringing hope back to Percier and they resume their wish.
Chloe is left alone and is forced to walk back to base after having her machine and communication device destroyed. She runs into a blizzard on the way and stumbles into a silver haired child, assumed to be the Professor's reincarnation.
