- Dr. Egan, (dubbed Dr. Evil) the principal who hates Griffin and could gain the ring as a football collectors item, as he loves the sport.
- Celia White, A nosy reporter who is digging up dirt on Griffin. She often twists his words, and she will do anything to make him look guilty, possibly to gain a promotion.
- Darren Vader, A burly boy who annoys Griffin. He could steal the ring after finding Griffin's retainer in order to gain profit. His motive for framing Griffin would be to distract the police from him.
- A boy who claims he is the rightful owner of the ring.
Griffin tries to get the suspects through a metal detector at the courthouse after sending them an anonymous e-mail stating that a buyer was interested in purchasing a valuable possession that "recently" came to them. Griffin unfortunately discovers that Dr. Egan is the only suspect left. Logan, Griffin's friend and amateur actor, agrees to get to know Egan's daughter so he can search the house and find the ring, getting him off the hook. The plan fails when they discover Egan does not have the ring. Griffin is tried and placed under house arrest, where his friends meet him via video chat and formulate a final plan to clear their friend's name. Savannah, the animal lover of the group finds that a type of mouse that is attracted to shiny objects may have found Griffin's lost retainer and swapped it out with the ring. Melissa, (the computer whiz) hacks into Griffin's house arrest system that allows him to leave the house without the alarm coming off while his parents are out. At the school during its play, Hail Caesar!, Griffin leads Egan to the mouse's nest and clears his name. He is then raced home and resets his house arrest anklet as his parents arrive. Egan, who got Griffin home in time, clears up matters and apologizes to Griffin, saying that he was wrong to judge him. Also, Celia White shows up in an attempt to get a story on him. Before she can twist the words, however, Egan makes her stop and makes sure she won't be doing it again. After this, Griffin asks the court if it will take a truly good-hearted friend out of the state school, so he can have a chance at life. They accept and it is implied that life will be better for Griffin and his friends.
