21: You might like this.

"You might like this," Gwen said.

She held up a plastic bag with a giant red suit in it. It was a unicorn, complete with horn and sparkley silver spandex tights. "Guinevere, I don't think I'm the one who would like this," he chuckled, which was rewarded with balled-up fists to his biceps. "Okay, okay, I'm kidding. But you can't deny that it would make your evening…"

"Arthur Pendragon, I am going to kill you," Gwen said, emphasizing the word kill. Arthur reached up and pulled a costume off the rack beside copies of his.

"Hmm," he said, putting his free hand to his chin. "Look, Gwen, it's a cat! It has lacy stockings and a leather bra and paws and a headband and a tail! Oh man, Gwen, you'd look great. Better than the model." More punches.

"You might like this," Gwen said a little while later as they delved further and further into the adult costume section. She handed him a costume. It was a donkey mask with oversized teeth and big bulging eyes and he could see using the example photo that the wearer saw through the nostrils on the snout. Arthur laughed and put it back.

"Okay, come on, time to find some real costumes," Arthur said, wrapping his arm around Gwen's shoulders, pulling her away from the kitten costumes hanging from racks. She threw her head back in laughter and reluctantly followed him along, pointing out couple costumes on the way. None of them were good enough. They wanted a really cool, good-looking couple costume. One that was believable for the both of them. Although Gwen could be anything and it would look great on her. To be honest, she could be wearing a rag and still look good. He pulled his arm away and waited about two seconds before she pulled on it again.

"Look, look, you might like this one" she said, pointing at a big plastic bag hanging from a really high rack. The costume's title was 'Regal King and Queen'. The male costume was chainmail and a scarlet red cape and a crown; the female costume was a long red dress with jewels around the neckline and a small tiara. Arthur smiled.

"Gwen, I don't like it," he told her. "I love it."
