Mega'an, Artemis, and Zatanna had binge watched BBC's Merlin during a three day lull in crime fighting. Afterward, Mega'an began making her eyes change to a gold color every time she uses telekinesis or any of her other abilities, to the amusement of the girls and Nightwing, who has also seen the show.
During a mission, Nightwing called Arsenal a prat and the girls all squealed in delight. Nightwing was so Merlin and Arsenal was a perfect Arthur. Through the rest of the mission the feminine trio and Nightwing began comparing their team mates to Merlin characters. Kidflash, they decided, was Gwaine. Superboy was a perfect Percival and Aqualad could totally pass for Leon.
Things only got funnier when Nightwing was called to meet Batman. As he was leaving, he turned to the girls and said. "I gotta go. Kilgharrah is calling." before stepping into the Zeta Tube. As the girls broke down laughing, Wally was confused. Wondering what all this was about, Wally watched the entire series at high speed that night.
The next morning, Wally had made a list of Merlin villains that he thought matched ones that the team had fought. The rest of the day was spent with Kidflash, Nightwing, Mega'an, Artemis, and Zatanna all comparing people in the League and Villains to all the characters in the show.
Across the room Connor, Keldar, and Roy were watching the show so that they would know what the rest of the team was talking about. After a week, they all agreed. Batman was so Kilgharrah.
