Sebastian was having a horrible time.
William T. Spears had indeed paid for a room, but he only paid for one room, with only one bed—which meant that he and Grell would have to share it.
Sebastian was sitting at the desk in the room, reading, when Grell stepped out of the bathroom, wearing the sexiest lady's negligee that would fit him. Few things terrify a demon, but when Grell stepped out, grinning and winking, Sebastian very quickly remembered what true fear was.
But he was a demon, and if there's one thing demons are good at, it's fighting back their urges. Sebastian easily held back the urge to run to London and nail boards over every door and window and instead rose up.
Grell curled up on one side of the bed, batting his false eyelashes. Sebastian shuddered and lay down on the other side, as far away as he could without falling off.
There was silence for a time, then Grell scooted closer to Sebastian.
"It's cold tonight, isn't it?" he whispered.
"Use a blanket," Sebastian said.
Grell giggled and moved closer.
"Bassy," he whispered, "aren't you tempted?"
"If you snore I'm kicking you."
"I mean, a handsome man like you…a pretty girl like me…"
"Beauty is in the eye of the beholder."
"We're all alone…in the same room…in the same bed…"
"I'm too tired to do anything strenuous."
"Bassy!" Grell said and leapt on him.
Things happened rather quickly after that. Sebastian grabbed a pillow and was able to knock Grell out of midair with it. Then he rolled out of bed and threw a sheet over him, which gave him just enough time to dart for the bathroom and slam the door closed and lock it.
There was more silence, and then a knock on the door.
"Bassy?" Grell cooed.
Sebastian pressed his back against the door, already plotting an escape route.
"Bassy, I'm sorry. Won't you please come out?"
"No."
"I won't do it again."
He scoffed.
Eventually the knocking died away, but he remained vigilant. About three hours later, there was another knock on the door.
"Bassy, please open the door," Grell whined.
"No."
"But I have to use the necessary!"
"There's a perfectly fine window in there."
"But I can't go like that! That wouldn't be ladylike."
"Perish the thought that you should do anything unladylike," Sebastian mumbled.
"What was that?"
"Nothing."
Another hour passed and again Grell knocked.
"Bassy, please, I've really got to go…"
"Hold it until morning."
"But I'm going to explode!"
"All the better then."
"You're so mean!"
"You actually sound surprised."
Another hour, another knock.
"Bassy, this is taking sadism to a whole other level. Please open the door."
"No."
"But why not?"
"Because I don't trust you."
"I bet that if I was Eleanora you would open the door."
"Grell, if you were my own mother I still wouldn't open the door."
"But…but…please!"
"No."
Sebastian remained pressed against the door until he saw the sun come out. Then he left the bathroom long enough to grab a change of clothes, and once he was properly dressed, he resumed his seat at the room desk and continued reading until Grell was ready to show him where the Reapers were.
