Answer:
If you're thinking he played the young character Frederick, Frazier and Lilith's only child, the answer is no. According to the Internet Movie Data Base imdb.com, Frederick was played from 1996 to 2003 by actor Trevor Einhorn, who does bear a resemblance to Jones. (Prior to Einhorn, Frederick was played by Luke Tarsitano in one episode in 1995). Einhorn is approximately five years older than Jones (Einhorn was born in November 1988, Jones in October 1993).
Trivia: Fans of the U.S. version of TV show "The Office" may have caught Trevor Einhorn as Justin, the potential intern, in the 2008 episode entitled Job Fair, in which Michael (Steve Carell) insults him by saying he's too goofy looking to be considered.
