The FBI order Jimmy to keep away from "their" case but things change, however, when Carter delivers interesting news about the latest victim.

Meanwhile, Kimberly's favourite teacher starts acting oddly and further tests reveal that a potentially fatal brain tumour is the cause of his erratic behaviour.
