Demetrius and his little sister, Meya wanted attention from his parents. He also said that he wanted to go on a vacation without Adam. Like Meya, Demetrius was very well-behaved, and thus seldom seen in this episode due to the focus on Adam.
He was 9 years old when he was on the show. As of 2017, he is 22 years old.
