I think Annabelle is from the functionaries "family" (or group, or whatever they are), Dont have much evidence to support this, aside from the fact that Annabelles mother is one of the people who attended the party and the meeting on Tuesday.
Which I think
Automated Senpai caught, I dont have any idea what this would mean for the story yet, maybe there is a small group of functionaries who only serve to spike the gene pool every few generations
Annabelle is still a huge mystery, I am excited to learn more about her
Nice pickup!
I went back and checked, and the screen before that provides a bit more info...
If the connection is correct, then it would seem Annabelle might be related to a 'regular petitioner' (rather than a functionary)...which may or may not be a family member, but given that family members can raise issues before the council, I'd imagine they probably are.
If she is, it's most likely a 'not so close' one...similar to Chloe at school...One of a multitude of nieces of some FF head or something. (I'd actually assume such people are the majority of the FFs).
Still, being something of a regular petitioner would explain at least some of her interest in the MC...She wants/needs his support for whatever she and her family petition for, and given how determined she is to get to know him, it seems she/they want it quite badly.
I wonder what she can/will offer in return though, especially as she's not joining the Harem...It's possible that mixing in those circles might means she's picked up some information which could be useful to the MC.
3 options come to mind...
1) She helps MC establish/strengthen clan Fletcher, removing doubts about validity and/or adding some wealth/influence/power (not sure how this could happen, but to be fair, they do kind of need it...Currently the Fletchers make the Bennetts look powerful).
2) Providing info on Gloria Russell acting dishonourably enough to sway Mr Gilbert, both factionally and about Hannah. (this seems the most likely).
3) Assisting in Elizabeth's plans to tear down her mother. (this could flow on from '2', but is probably more a medium/long term thing...Much as I might like the drama stemming from having Brian heading the Russell family).
