Duncan started dating Angie Kurokami back in Winter 2009.
While he gets along very well with Kurt, he never get along with Jason, likely because he was not comfortable with the knowledge that he had dated Angie (long) before meeting him. This lead to them butting heads on numerous occasions, and they nearly came to blows over an argument about his and Angie’s roles in the gang’s zombie movie, which lead to Angie quitting both the production and the movie theater.
While they were still filming the gang's zombie movie, though, Duncan proposed to Angie, and she accepted. Duncan and Angie were married in June, 2012.
He has a tattoo of a dragon on his right arm, and (like Angie) he likes horror movies.
