The whole point of the quirk is that she wants some form of
control in her life.
I forget where but
Tommy7358 might know since he decided to read the entire thread.
Basically I went full psychologist mode and explained that the Big Sis Complex thing was her wanting to nurture Null. This is why she gets pushy about studying and spending too much time slacking off.
The faux-incest kink is something that's supposed to develop over time after you initiate a sexual relationship with her.
It's the same reason for the other girls having their quirks moved to relationships.
Laura stalked other members of the X-Men, notably Logan, without it being sexual and Rogue has had many moments of insecurity in her life even when she's been depicted at her most confident.
However, we wrote the quirks to inherently come off as if you are romantically or sexually involved with them. The reason why they can't be activated right now unless you're dating them is because the platonic content... doesn't exist yet. When our writers finish writing the content, you'll be able to activate it while being their friends.
Yes I will bully the writers to having platonic Big Sis Jean failing miserably at being subtle in thinking her lil'bro deserves a respectable and put together girl,
such as herself, and not any hussies who don't have their focus on Null's future.
