In 2003, when "Law and Order: Special Victims Unit" was in its () season, Ian Somerhalder starred in an episode called "Dominance" as a man named Charlie Baker (via Law and Order Fandom). While Somerhalder's portrayal of Damon Salvatore was complex, as the character committed some serious atrocities, he also had another side to him. We won't spoil the episode for you, but we will say that there may be little less to love about the one-off character Charlie Baker. 

The episode centers around a sexual homicide that kicks off a rampage of killings (via IMDB). When homicide detectives get involved, the team chases clues in a race against time to stop any further violence. At the end of their trail, they find the superintendent of a building and his two sons, one of whom is played by Somerhalder. If you want to know what happens, you'll just have to go back and watch!
