NEW YORK, Jan. 18 (UPI) -- Dexter Sol Ansell and Peter Claffey say their characters' glaringly obvious contradictions are what make Dunk and Egg such a good team in the new Game of Thrones prequel, A Knight of the Seven Kingdoms.

"You wouldn't think they would really get along, but when you actually get them together, Egg learns so many different things from Dunk and Dunk learns so many different things from Egg," Dexter, 11, told UPI in a recent round-table interview with reporters at New York Comic Con. "It kind of works."

"There is a symbiosis of knowledge and navigation through this world, especially in the first couple of episodes. It shines through even more when they are not fully sure who either of each other is," noted Claffey, 29. "The fact that it maintains like that is a really lovely relationship to play on screen."

Premiering Sunday on HBO, the six-episode fantasy drama is based on the Tales of Dunk and Egg novellas by George R.R. Martin, which take place about 100 years before the events of Game of Thrones.

The prequel follows an ambitious hedge knight named Ser Duncan the Tall (Claffey) and his precocious boy squire Egg (Dexter).
