'Teen Wolf' Season 4: 'Flowers in the Attic,' 'Ender's Game' actors cast
Dye's Garrett is a new student at the school, according to E! Online, while Mason is a freshman described as funny and gay -- but not in a stereotypical way.
Both characters will recur several times in the upcoming season. Dylan Sprayberry ("Man of Steel") will also recur as still another lacrosse player, Liam. Casting for one more character, new math teacher Ms. Fleming, has not yet been announced.
With at least one major character reportedly dying before the end of Season 3, all of these new additions might be necessary. "Teen Wolf" currently airs Mondays at 10 p.m. ET/PT on MTV. Season 4 is expected to premiere later in 2014.
