It's been pretty well known that "Game of Thrones" season six will delve more into the stories of the Greyjoy and Tarly families, and in order to do this, they will be introducing more characters into the show.

Just recently, they cast Danish actor Pilou Asbæk to play the threatening pirate Euron Greyjoy for season six, and now, they have cast "UnREAL" star Freddie Stroma to play the favored son Dickon Tarly, according to Entertainment Weekly.

Little is known about Dickon in the books written by George R.R. Martin, save for the fact that he is the second son and favorite child of Lord Randyll Tarly. Unlike his elder brother Sam, Dickon is spirited and athletic, and his qualities were the ones Lord Randyll looked for in Sam, who unfortunately lacked it.

Because of his disappointment in his eldest son, Lord Randyll cruelly made Sam choose between death and signing up for the Night's Watch. Sam chose the latter, and therefore Dickon became his heir.

As for Stroma, he is best known for his role in the drama slash comedy UnREAL. In it, he plays a highly sought-after bachelor in a fictionalized version of the reality show "The Bachelor." He also appeared in the last two "Harry Potter" films as the confident Gryffindor Cormac McLaggen, who was Hermione Granger's one-time date in Professor Horace Slughorn's parties.

Stroma also appeared in the Michael Bay film "13 Hours: The Secret Soldiers of Benghazi."

People have gotten to know Theon Greyjoy (now Reeks) and Samwell Tarly pretty well over the past five seasons of "Game of Thrones," so it would be pretty exciting to get to know some of their other family members this time around.

Theon is a close friend of Stark kids who turned on the family upon the insistence of his father Lord Balon Greyjoy. However, all of Theon's plans came crumbling down when he fell into the hands of the sadistic Ramsay Bolton, who tortured him relentlessly until he assumed the identity of "Reeks."

As for Sam, he is the close friend of Jon Snow from the Night's Watch. He is big, awkward, and branded as a coward, but he has a deep passion for the written word and Jon has been very protective of him ever since they became "brothers." The last people saw of him, he was bidding goodbye to Jon (before the other brothers turned on him and stabbed him to death) and leaving Castle Black with Gilly. They are heading towards Old Town where he can study to become a maester.
