>>49437231>she is a dangerous and self-destructive girl who enjoys breaking what is important to others and herself>she is literally addicted to destroying things and can't stop.I've written the "getting hired as a butler at the SDM" premise a couple times, and my general idea around Flan is that she's nuts, but not as impulsive as she appears. The things she does follow a consistent, internal logic, so if she believes there's more fun to be squeezed out of something by taking her time destroying it, she'll gladly hold off. So, the way I've written one progression is that she starts by strangling the butler on impulse, only to be stopped by Remilia because by this point he's piqued the lady's interest, so Flandere bides her time, suppresses her spontaneous destruction instincts, and eventually learns that the butler is Catholic and has been praying in secret. She rats to Remilia, who's infuriated that the butler had sworn an oath to serve only her, but by nature of his religion also served God. Remilia tortures him, sticks him in an oubliette, trying to get him to recant, and eventually exiles him when he doesn't. Flandere finds this massively entertaining because she gets to watch the slow destruction of her sisters happiness, as she tries in vein to claw back the Butler's loyalty, and the butler's sanity, since he did technically lie to Remilia when making his oath, and lying's a big no-no in Christianity.
In essence, I think Flandere might really like blowing stuff up, but she'd also play the long-game if she see's an opportunity to do so.
Post-exile I'm not quite sure how to write Flan. On one hand she might just move on since she had her fun, but on the other if the Butler was still faithful she'd want to wreck that as well. There's also an idea I've had for the scene where the Butler is leaving the mansion and Flandere heckles him, telling him things like "it's your own fault for lying" and "you must really hate me huh?", to which the Butler has a thought he knows he shouldn't express, but he's lost his restraint at this point so he says it anyway: "I don't know, I never really thought of you as a person." Which takes Flan from an extreme high to an extreme low. She gets her kicks from destroying things and expressing herself through carnage, because it's something she's not supposed to do, but if someone doesn't resent her for it, there's not point in the deviancy, it'd be the same as not acknowledging her existence at all. It feels a little indulgent, but I like the idea of Flan faces unconventional consequences. Whatever the case, any relationship with Flan would be a strange one.
