"Good. I already did blues. I’d rather be purple than green inside. Wouldn’t you?" Crowley took a little match box out of his breast pocket and slid it open. Inside was a single, glowing red beetle, about the size of a ladybug. He poked it until it started moving. It crawled onto Crowley’s hand and found a vein. Began to bite down. Crowley’s hand twitched, but he didn’t bat an eyelash at it, merely watching with mild interest. "Meet Bitey. He’s my little red pill."
Spike had been expecting an actual gel capsule or solid colored pill. He lifted a scarred brow at the little beetle. Well, it couldn’t have been worse that that things that Giles had had burrow into his skull about a decade ago.
He watched the little creature do his thing with interest as it worked its magic on Crowley, “And whut does Bitey do when he gives you his little treat? Or I should say, what is his treat?”
