Well no one has really given her cause to hate, and when she doesn't like someone they will know. There's a couple of people she just hasn't hung out with to form an opinion of, though.
Closest to dislike she has is Ace, who she just thinks is dangerously unstable and is in need of prolonged mental healthcare. She's probably going to haaaaaate Aaron Grant, if she learns about the fire thing. Uso was iffy, but she was deemed cute upon terror of spiderbots.
The rest of you will be her friend someday, when you least expect it. Except Truffleclub and Sammy, who have earned outright doting.
