O’Brien stars as the character Stiles in the show’s fourth season. Stiles and his friends deal with tragey, and face a new enemy known as The Benefactor. Co-stars Tyler Posey, Tyler Hoechlin, Holland Roden, Shelley Hennig, and Arden Cho.
The second half of the season, fans will finally get to see who The Benefactor is — the bad guy basically of the season. That will be revealed and then it always sort of finds a way to get flipped on its head and it’s like not what you think. That’s always all kinds of fun and it leads into this crazy finale where basically everybody’s life is on the line.
