FORCED ROOMIES—PART THREE: 'jerk.'; 'bitch'

"No, no, NO!" Buffy screamed. She realized she had no clothes in Giles' apartment. "Damn!"
"What the bloody hell is so important you have to wake me up for it, Summers?" Spike yelled from the other room. "Anything's more important than your rest, Spike. You're a pain in the ass!"
"Likewise, Slayer," he screamed back at her.
"Well, unlike you, my beauty sleep is the most important thing of the day."
"That's because unlike you, I don't need a beauty sleep."
"You think you're so pretty?"
"Oh, please. The Judge is better looking than you are, Slayer," Spike said and emerged from his room.

An hour later, they were sitting in Giles' kitchen. "So, how do we undo this barrier spell thingy?"
"We can't reverse the spell. Only the caster can."
"Why can't we?"
"Because that's how the spell works."
"That's stupid!"
"Magicks work like magicks work. This one works in a way that gives the caster the control over the barrier."
"Well it sucks," Buffy said, throwing her fork down and glaring at her fellow prisoner of their own behavior.
"It's the way it works, Slayer!"
"How do I know this isn't all your fault anyway? You seem to know an awful lot about it."
"Would I actually voluntarily lock myself in with the person I hate most in the world?"
"Hmm, I always did think you had a few loose wires up there," Buffy said, tapping her forehead with her finger. "A century with Dru can't be good for ones mental health."
Spike ignored her. It wasn't like he wasn't used to being insulted. "Besides, you haven't seen me walk out that door, have you?"
"Prove to me that you can't walk out of the door."
Spike got up and walked to the door. He glared at Buffy but opened the door anyway and walked straight into the barrier. The blocking magic slammed into him at full force and made him come crashing into Buffy. In perfect unison the muttered: "I hate you," and then said, "Stupid vampire," and, "Damn Slayer," out loud and simultaneously. Frustrated, Spike got off the floor and stalked up to his room. When he was halfway up the stairs he turned around; Buffy did the same on her way to the couch.
"Jerk."
"Bitch."
And then they both went their own separate ways.
