But let's not forget about Ari's personality and position. She's Head of Intelligence, which means she respects those who are, well, intelligent and she knows Aerous is not. She values brains over brawn. This doesn't mean she cannot respect his strength (because she does) it means she won't openly or directly show it to him and if she does it'll be in a sarcastic/mockingly way. I said this before but showing him would mean she cared about him and caring, to her, is weakness.
She'll give Aerous a lot more respect than she would say Tobi, Annabelle, or Xoxaa. Ari's vindictive towards everyone it's just her thing. Plus, she's protective over Camellia since that's her right hand gal pal and she doesn't want Camellia distracted by flirtatious guys.
Everyone's a hater! :P That's okay Ari's not too fond of newbies. Her shyness will drive Ari crazy because she likes it when people are blunt and take charge like her.
I think it'll be fun to have Ari have a little crush on Marcus even if he won't return any of her so-called affection. She might just ask him to dance at the ball.
