LIAM DUNBAR (Dylan Sprayberry) - The newest member of Scott's pack and his first true Beta, Liam still struggles at times with the whole 'being a teen wolf' thing. But with Scott as his leader and mentor, they have continued to tame Liam's anger. This proves to be difficult at times since his best friend Mason has no idea what Liam is and what he's been up to with Scott's pack. To make matters worse, a familiar face from Liam's past resurfaces at the start of his Sophomore Year.
