Spike watched as her expression shifted from incredulous disbelief back into the confused, suspicous one she'd been wearing moments ago. And now he had a gun pointed at him. Tonight was shaping up to be great. Really, it was. "My name's Spike," he said, holding his hands up to show her he had nothing on him. Not even a bloody pack of cigarettes. Fucking Seal. "And I don't have an agenda. I know it's mad, but...it's true."
He slowly lowered his hands again, keeping his stance neutral in some small attempt to keep her calmer. "Look, it's only going to sound even more nuts explained in full, but there's an Apocalypse going on here, Lucifer, demons, the whole shebang. Devil got out of his hell cage and one of the seals keeping him there ripped a hole in time and space, started having people from all sorts of different dimensions filter in. People from other words, people from fiction. It sounds crazy, but I swear to you, it's true."
He paused in his explanation for a moment to consider something. "I can show you," he said cautiously, "Prove it to you. If you promise not to shoot me." Spike wasn't even sure he could take her at her word, but it was worth a try anyway.
