Supernatural's spin-off Supernatural: Tribes has cast (another) Vampire Diaries alum, as well as a former Heroes actress, for lead roles, according to spoilers from TV Line.
Stephen Martines, who most recently played vampire Frederick on TVD in Seasons 1 and 3, will portray Detective Freddie Costa, "a world-weary Chicago cop who serves as a mentor to Ennis (Lucien Laviscount), but also is secretly on the payroll of one of the monster families."
Danielle Savre from Heroes will portray shapeshifter Margo, "who serves as the acting head of the leading shapeshifter clan. She’s an ex-punk rocker-turned-corporate professional who feels threatened only by the return of her prodigal brother David (played by Nathaniel Buzolic)."
Savre and Martines will both appear in Supernatural's 20th episode, which is Tribes' pilot, airing April 29.
