To be fair, one of them is a Githyanki, one is a (raised) Lolth-sworn drow, one is a Sharran, and one is not human, nor raised with human (ish) social values. It's not out of character for any of them to feel so. It could be an accident that SH is the only one with a not "we'll bang, okay?" outlook. But, if you make the profound mistake of raising approval beyond a limit, you're certainly a piece of meat surrounded by lions in this game lol
