Jake and Gaia meet in book 25 in their gym class. Jake, the new kid in the school, comes up to Gaia and says that he's, 'a black belt and I'm bored'. He asks her if she can fight and when she says yes he challenges her. He comes up the bleachers just as Gaia and Ed were about to kiss and Ed, deep down, is worried about Gaia liking the new guy.

Although there is some 'mutual ass-kicking', Gaia beats Jake, going quickly into the locker room after to make sure nobody sees her pass out. Later on, Jake and Gaia start to get to know each other, slowly but surely, and Gaia calls him from Fort Myers, Florida, after she is kidnapped by the Organization and brainwashed. This is because he was with her in Washington Square Park when it happened. Jake helps to rescue her and later helps her to rescue her father from Siberia.

Through all of this, and the karate team, she and Jake get closer. When Ed leaves her and Sam leaves the apartment, Gaia is alone once again and gets together with Jake. This is also when Jake helps Gaia fight off Tatiana and get her arrested. Originally Jake was interested with Gaia because she wasn't attracted to him like any of the other girls in their school and she could beat him at martial arts.

Later, when Gaia is brainwashed by Skyler after she takes the 'fear serum' and temporarily gets the fear gene, Jake realizes that something is wrong and helps Oliver, who is slowly but surely reverting back to Loki, to save her once again. In the final rescue though, Jake is killed while saving her. After the 'Curse of Gaia' claims another victim, Gaia leaves New York City after saying good-bye to Ed.
