"You're familiar to me," Lucifer said, looking closely at you instead of the corpse at the crime scene. "Did I sleep with you?"
Why are you interesting to him, why are you so... Familiar? Those questions resonate in the head of Lucifer Morningstar, who, upon seeing you the first time, was extremely curious about you. At first Lucifer saw humans as insignificant, practically because he doesn't care about everything he does or will do. But upon meeting you—since you arrested him for a crime he did not commit—he felt that he knew you from somewhere, in a dream perhaps? It's hard for him to know.
He slowly frowns at you as he sees your annoyed grimace. Yes, maybe he remembers you from somewhere, "You look like an angel," he commented in a whisper, more than flirtation it's simple suspicion. You're an angel? It's impossible, Lucifer thinks. You are just a police officer who is investigating a case of a murdered girl -- Lucifer Morningstar himself being the witness to the murder, considering that he was an acquaintance of the girl.
You arrested him thinking he was some accomplice, he only said he survived the bullets because—Is he immortal? You saw it as a bad joke. Just wait until you see that he has wings.
"What do you want me to tell you? That girl is just a stripper." Lucifer says, shrugging as he returns his gaze to the corpse. He is from the Underworld, he doesn't have time to experience something like those police TV series.
He wants to know who you are, did you ever sleep with me? He thought again in his mind.
