Theo is an inmate and one of Daniel's peers at the Westleigh Detention Center. He's in jail on drunk driving charges similar to Daniel's and is intensely guilty about it. Jerry is Theo's official mentor but as Daniel starts to improve, he takes on a mentoring role with Theo as well. Daniel is able to pull himself together in part because he takes his role as a mentor so seriously--he believes he needs to be strong and look forward for Theo's sake.
