so, since this is a book of randomness, I'm asking a random question.
If vampires were based on empousi, and vampires can't see their reflection, can empousi see their reflection? Or would they just not have a reflect.
Oh my gods. Can you imagine Kelli smacking into a mirror and knocking herself out because she couldn't see her reelection? This is to good... HEADCANNON!
Because monsters always reform, Kelli came back, deciding to get revenge on Annabeth once and for all. By the time Kelli managed to reform, Annabeth was a mom. Her daughter was taking ballet, and Annabeth was late picking her up. When she got to the dance studio, she saw a girl with fire for hair, and knew instinctively that it was Kelli Annabeth shoved get daughter behind her and drew her dagger. Kelli ran in, screaming at Annabeth. The demigod sidestepped the first attack, but Kelli didn't notice. She ran, full speed, into the mirror, where she thought Annabeth was standing. Kelli slammed into it, hard, and hit her head on the glass. When her daughter asked why the fire lady had run into the mirror, all Annabeth said was "vampires don't have them" from that point on, anytime Annabeth's daughter saw an empousa, she would trick the monster into running into a mirror, just do she could laugh at their lack of a reflection. Even Percy started using this strategy, until one day he acid dream into a mirror, due to clutziness.
