James P. "Junior" Rennie, Jr. (d. 26 Oct, Year of the Dome) is the son of Jim Rennie, and a resident of Chester's Mill, Maine. He is friends with Frank DeLesseps, Melvin Searles, and Carter Thibodeau. He suffers intense migraines, for which he was prescribed Imitrex by Dr. Haskell; the headaches are, however, a result of a brain tumor that Haskell failed to diagnose. The migraines are partially responsible for his propensity for violence. Meanwhile he did not know that people were planning to rescue Barbie. Romeo Burpee and Jackie Wettington enter the police station.
