Lorne Banner

Season 1
Banner first appears in "Graze Crescent ", where he is seen leading a group of hunters who call themselves the Orions hunting down Ingrid. Though, he was not properly introduced in the sequence, he finally introduces himself the next day as the school's new history teacher. In "The Verge of the Bolide ", he is seen with Peter confronting Nee about Eric's misdemeanor, memorably pointing out if Eric had not eaten food for awhile (suggesting indirectly that he maybe is a newborn vampire).
