Sam jolted straight up at the sound of the baying, reaching for his gun before he'd even stopped to think about it. He knew that sound couldn't be good, even before Gabriel confirmed it.

"Fucker's fast." There's no way he should have made it there so quickly. Unless, of course, he'd decided to shift back to human and actually drive. Sam gritted his teeth, sliding out of bed and opening his arm for Gabriel to come with him. "I'm up," he called out to Dean. "Call the police. I alerted them earlier that there was a pack dispute that might make its way here. I'll get hold of building security."

He'd wanted this out in the open and ready to deal with if Lucifer made it necessary. Which, it seemed, he just had.
