Man, Jill isn't obnoxious compared to the other Alpha nu Omegas, especially for someone with her last name, but her reactions to not going with her in Ep 6 really remind you that she's still entitled to an extent. Like, the MC even states that the reason he can't go to her completely unplanned surprise date with him is because he has to go help a friend (granted, that friend is Sage, but still).
Granted, she did go out of her way to try to stop Tyballs from suing the MC. I dunno. Just seems like she's got a lot of expectations towards the MC. Then again, as a Royce, I guess she grew up with expectations forced upon her so she probably sees that as normal for everybody else.
