From my point of view, there's a helpless, trapped hero sidekick who I could do with whatever I wanted and if I felt that way inclined, I could even make sure that you couldn't scream." Hartley set the flute down and pushed away from the desk, walking toward Cisco. He put a hand down on his chest and smiled down at him, sweet enough with that devilish edge to it. "It's a very cute look on you, Cisquito."
