Man I wish there was a movie on Jane & Alec Volturi. Imagine how interesting that would be with the twins having actual personalities besides just killing.
Imagine the unaware vampires perception on them of those two just being harmless little kids and being proven wrong.
Imagine their sibling bond and how the writers would've played into that.
Or
Aged up! twins where one finds their intended (or whatever it was called) and how it affects their bond exactly.
Digging into their past ofc and giving them the desired affect so we might actually find them kinda scary.
Maybe even their relationship with every Volturi member and how it differs. Hell even their relations with the Cullen's!
They could've called it 'blood moon' or something.
