In season 3 of The Lair, Sheriff Trout is haunted by his ex-roommate, a young hottie he appeared to be helping get his life on track. Slowly through the season we are introduced to Dennis through flashbacks and to the story of his disappearance and Trout’s suspicious that a drug dealer killed Dennis. Someone seems to be outside Trout’s house, and finally at the end of season 3, Dennis returns home, a vampire.
Dennis is played by Norwegian actor/modal/hottie Thor Knai. With any luck he will return in season 4 of the Lair, assuming it gets announced.
