|“||You don’t even know what’s happening, do you? Soon, your pretty little camp in flames, your friends made slaves to the Lord of Time, and there’s nothing you can do to stop it. It would be merciful to end your life now, before you have to see that.||”|
In Percy's dreams, Kelli always sensed that he was watching. She tries to bite him every time, causing Percy to wake up.
While Percy falls asleep, he watches his dreams like spying and pretty much every time he has a dream about Luke, she is in it and she knows that he is "spying" on them and tries to kill him right before he wakes up. Apparently, she also tries to flirt with Luke but he does not trust her because of what she did to another boy in Seattle Washington.
While pretending to be a normal cheerleader, Kelli is a valley and alluring girl, but is cruel and merciless in her true form.
Kelli is an empousa, who are the servants of the goddess Hecate. In true form, she has completely white skin, flaming hair, fangs, one bronze leg and one donkey leg, and red eyes. When in human form she appears as a pretty African American girl with curly hair. Percy describes the hair as "curly hair like Medusa's".
