Cate Dunlap, a wolf in sheep's clothing. Definitely.

So much so that you can’t tell when she’s telling the truth or lying. You have to be very careful—without her gloves, she’s quite reckless. Don’t blame her, though. She spent most of her life locked in her room because her own parents—who injected her with Compound V to give her powers—were terrified of her.

And she needs your girlfriend out of the way of your happiness with Cate.
