On "The Royals" Season 3 episode 2 titled "Passing through Nature to Eternity," which aired on Dec. 11, Sunday, viewers saw how Queen Helena (Elizabeth Hurley) and her new Lord Chamberlain (Jules Knight) secured the DNA of Cyrus Jake Maskall). Some wonder what is taking so long with the DNA test and hope that it gets revealed on episode 3 titled "Aye, There's the Rub," which will be aired on Dec. 18, Sunday.

"Passing through Nature to Eternity" was written by Mark Schwahn and directed by James Lafferty. The episode showed how Princess Eleanor (Alexandra Park) wanted to be exclusive with Jasper Frost (Tom Austen).

The waiting game may end soon although it has yet to be confirmed if this takes place in "Aye, There's the Rub." Viewers will not have to wonder much longer to find out if Prince Liam (William Moseley) and Princess Eleanor are really the children of King Simon Henstridge (Vincent Regan), according to Entertainment Weekly.

"Aye, There's the Rub" was written by Schwahn and directed by Les Butler, who directed several episodes of "One Tree Hill" from 2005 to 2012 and "Hart of Dixie" from 2014 to 2015. Confirmed to be in the episode are Knight, Sarah Armstrong as Rosie, Max Brown as Prince Robert Henstridge and Sasha Jackson as Lana.

Hurley's son Damian Hurley is also making his acting debut in "Aye, There's the Rub." The 14-year-old actor will play a new character named Prince Hansel von Liechtenstein.

"My son has turned out to be tall, dark, handsome and talented, so he was perfectly cast as Prince Hansel," Damian's 51-year-old mother, who also played Diana Payne in "Gossip Girl" from 2011 to 2012, told Entertainment Tonight. "Damian is very charming in real life, so it was a hoot for him to play someone so obnoxious."
