After Sergeant Neff takes over as platoon officer, while Teddy and the platoon are waiting outside his office, Teddy mocks the late Robert Thorn in front of his friends. When Teddy then mocks the Thorn family in front Mark, Mark hits Teddy; causing Teddy to beat Mark up. Damien intervenes and uses his powers to torture Teddy with what appear to be nightmarish visions, until Neff breaks Damien's focus.
Some days later, Damien takes Mark and their academy platoon, including Teddy, on a field trip to a chemical plant. When toxic fumes escape at the plant, Teddy and the other cadets except Damien suffer mild chemical poisoning and are temporarily hospitalized. After Mark is killed by Damien, Teddy attends Mark's funeral.
Teddy outwardly mocked Mark's family in front of him, then beat Mark up when the latter retaliated. Despite the hatred between the two, they do eventually become friends, and Teddy later attends Mark's funeral.
When Teddy mocked Damien's late father, Damien warned Teddy not to do so again, which apparently caused Teddy to see Damien as an egomaniac. Damien also tortured Teddy with horrific visions for beating up Mark.
