DISCLAIMER- I do not own The X Files, The Lone Gunmen, or any of these characters. I just couldn't leave things like this, so I'm taking matters into my own hands and writing my version of what happens between Byers and Susanne after the events of Three of a Kind.
After putting the girls to bed and showering, Byers pulled a clean t shirt over his newly dried skin. Water droplets dripped from his hair, soaking the neckline, before he rubbed a towel on his head. Susanne was in the bathroom, brushing her teeth.
"You forgot something," she called from the door.
Byers squeezed his eyes shut. He always forgot to put his old clothes in the hamper. Always. She even moved it into the bathroom, and he still forgot.
"Sorry, honey." just as he was about to go back into the bathroom, she came out. Byers's eyes widened. He gaped for a moment, before smiling warmly and blushing.
"It's okay," she strode in nonchalantly. His old work shirt was the only piece of clothing covering her body. It was buttoned halfway, so he could see nearly everything, with hidden, enticing places beckoning. Her body wasn't anything new, but even after ten years of marriage and two kids, she could always get to him. She wrapped her arms around his neck, and kissed him. His arms encircled her waist, and she walked him backwards towards the bed. As they fell into the clean sheets, her lips met his ear.
"Don't get used to this," she whispered. "I will get angry next time."
Byers awoke alone in his bed. The room was cold, and he could hear the tinny arcade music emanating from Langly's room down the hall. He sighed, covering his face with the pillow and gently beat his head against the mattress.
