Jermaine.After a bizarre dream, Finn and Jake venture to the home of their brother, Jermaine (voiced by Tom Scharpling). The duo journey to their old familial house, which is still inhabited by Jermaine. The building is surrounded by demons, which Jermaine vigilantly fends off. Jermaine eventually gets into a fight with Jake, pointing out that he has had to take care of their father's affairs, whereas Jake has gotten to lead a life of adventure. Once the tensions cool—and the brothers' home burns to the ground—amends are finally made.
