"Oh... That's... Nice, murder-friend. I appreciate it, I really do, but..."
That was awkward, yeah. Shimmer didn't want to be responsible for killing someone without due cause, but... Hmm, this was strange. He was right. About more than she would have guessed, actually. And, between this and casino-related monster attacks, was proving surprisingly effective for escorting duties, too!
"Uh... Hey! How about... Uh, hypnotise him? With your vampire super-powers? Or-or-or convince him? Or... Yeah!" And she hastily wrote down the name and contact details. "Make an anonymous call to the police! Say you saw him go in there and cause a ruckus! Yeah! And... And that's all I'm going to ask of you, because the less I know, the better. Which makes me the happiest little guilt-free Shimmer in all the land, thank you very much."
And she smiled a smile of white teeth, tucking the details into his hand. It would be better for her not to know what might happen if the vampire decided to go further. But now it was out of her hands and, well, into his. Another mystery solved! Yay!
"But next time I come find you, I'm going to out-sell the other guy. Deal?"
