For those writing relations about Eve, I would like to point out that not many people know she's a manipulative bitch unless your character has been personally destroyed by her or you're friends with her like Audrey. She's good at keeping her not so nice actions hidden. Don't get me wrong, she is a dominant person, but unless your character took the time to investigate incidents and find clues that went back to her that she is the one that ruined someone's reputation, all your character would see is someone who walks the halls with the head Prep, Audrey, whose pretty dominant herself, and can be quite harsh with her words if she doesn't like you. Your character can point out her talent, her ambition, and her sometimes cold queen nature if she isn't trying to get closer with you. But knowing she might be out to use you, not many people should know that. She's had plenty of years of building hatred and hiding her vulnerability to go unnoticed. 

I'm sorry if there was a misunderstanding with that, but not many people know they have a snake as a friend until the snake bites. 

If you want your character to have an inkling of an idea of Eve's hidden personality, pm me. Because we'll have to discuss a hell of a good reason. Eve is very clean when she metaphorically makes her kill. Imagine her to be like an assassin. You don't know who the assassin is until she makes the kill on you - even then, no one else knows who the assassin is. Like I said in her personality, for all you know, she may very well want to be your friend. Even if she may see you as a tool or an asset. Does your character know she sees you that way? Absolutely not.

The thing about good manipulative characters is hardly anyone knows they're manipulative.
