Sam Underwood has a thing for serial killers these days.

The young actor, currently recurring opposite Michael C. Hall on Dexter Season 8, will be a series regular on Season 2 of The Following.

According to TV Line, Underwood will portray Luke, a very complex and dangerous individual who may or may not be a follower of a returning Joe Carroll.

Luke is just one of three new characters who will come on board this Fox drama when Season 2 kicks off in early 2014.

Underwood, meanwhile, will also play a friend of Dana's on Homeland season 3.
