Danny Phantom

In this episode, Danny, Tucker and Sam leave the movie theater, Danny worried his sister might be nearby until his friends gives him the all clear. Danny's been trying to avoid his sister who, upon being a member of their team, has constantly been overprotective of him. Unfortunately for him, Jazz immediately arrives and shoves a Fenton Thermos onto him, crying out he should always have one in case of an emergency. A calm Danny reassures her to relax, saying he has everything generally well handled.

Skulker then appears, but he is clearly not on Danny's tail for once. Feeling rather rejected, Danny flies after him and catches him stealing bloodstream nanobots inside the Axion Lab. Danny and Skulker quickly battle with the latter trying to escape. Jazz comes over to help, trying to send a Fenton Thermos his way, but misses and gets Danny instead.

In school the next day, Jazz comes over to the trio to showcase her research she has done on Skulker or as she calls him "Ghost X" as well as create new witty banters. She walks off while Danny mumbles on how to deal with her, settling with the idea of not interfering much on her actions so she'll realize how incompetent she is in her ghost hunting skills. Predictably, her battles with the Lunch Lady Ghost, Klemper, and Box Ghost, all who turn out to be duds with her accidentally hurting Danny and sucking him up in the thermos again, but it does nothing to deterioate her spirit. As Jazz drives Danny home after their ghost hunting patrol, he again criticizes her.

Back in the Fenton household, the Fenton parents have made an Ecto Converter for their RV which turns a ghost's natural energy into fuel sources. Jazz then makes light of the secret she shares with Danny, much to his annoyance, then playfully slaps him in the back, causing him to touch the Ecto Converter and make the RV move while the parents are still in it. Later that night, Skulker sneaks up while Danny is asleep, searching for the Ecto Converter. Danny however manages to find him and does battle. Once again, Jazz joins in the battle and accidentally reveals the location of the Ecto Converter. Skulker takes what he came for and flies off.

By school the next day, Jazz finds the three hiding in a broom closet in school, to avoid her, despite Danny vehemently denying it, where she managed to hack into his files where he keeps a profile on all the ghosts, including Vlad Masters. Danny, angry at her for barging into his ghost hunting life, bluntly tells her she is terrible at it, causing her to get teary and run off in front of an angry mob of students.

At home, Danny is told by his parents Jazz is missing. Indeed, she ends up in Vlad's manor where she begs the rich millionaire to let her stay in his home, to which he quickly obliges. Jazz calls her parents and lets them know she wishes to stay with Vlad's for awhile, something Maddie isn't too keen on. Danny in the meantime leaves for the Ghost Zone, assuming she's out there to fight Skulker to prove him wrong, while the parents play checkers now that they are in an empty house. Danny catches Skulker stealing Technus' electric staff. After a short battle, Skulker shocks Danny with the staff, then stuffs him inside a transparent cube.

Jazz in the meantime spots Vlad going into his secret lab before hacking into his computer to find info on nanobots and Ecto Converters. Vlad however returns from his lab, so she quickly finds his college yearbook to which she looks at to hide her true intentions. She later sneaks into the lab where she finds the stolen items as well as the Fenton Ectoskeleton Vlad stole earlier. She is however caught by Vlad, but lies her way out and gets off scot free or so it seems. Skulker comes immediately afterwards with the electric staff and Danny. Seeing Jazz and Danny know each other, Vlad decides to test Jazz's loyalty.

In his backyard, on a football stadium, Jazz is now inside the improved Ectoskeleton suit, designed so that it won't waste her. She must battle Danny for Vlad's loyalty, something she doesn't want to do until Danny insults her. Danny tries to get her to listen to her, but she refuses, angering him further. The two then try to escape until they both run into a shield that works on both humans and ghosts, blocking their way out. Danny suggests they pretend to battle each other, but she senselessly beats him with seemingly no remorse. Danny, angry, manages to outdo Jazz and shouts at her, telling her to listen to him for once in her life, something she WAS doing by making the fight look convincing. Now in the plan, Danny, with Jazz continues to fake battle until Danny pretends to be gravely injured. Vlad then comes over to accept Jazz, but he ends up getting punched by her. Tricked by the two, Vlad turns ghost, but at that point, the siblings have escaped, leaving the Ectoskeleton suit to self-destruct nearby him.

As Jazz drives Danny home, Jazz states she'll continue helping him from the background by covering for him up front and Danny gratefully dubs her a Team Phantom reservist. Meanwhile, back in the Fenton household, Maddie cries in triumph for beating Jack in checkers.
