Jermaine, the brother of Jake, adoptive brother of Finn, and son of Joshua and Margaret, is introduced in "Crystals Have Power." He was first seen in one of Jake's flashbacks where they were both children. Jake hurt Jermaine in his past, which seems to have left an impact on Jake. Jake thought he killed him, but Jermaine, who was probably in a coma, managed to recover. It is unknown whether he, like Jake, possesses any powers. Jermaine can somehow contact his brother while they sleep, as Jermaine claims to have been asleep at the same time as Jake when he appeared in his dreams.
