Grimoire: The one with the face (its name eludes me, sorry ) and Jo Wyatt's or Alix Wilton Regan's voice.
Outfits: Eh... This is a hard one . I'd say probably the victory girl outfit for the White Coven MC, ze classic witch for the Secret Coven MC, something with a dashing black dress for Night Coven MC and something with lots of leather/ripped jeans + piercings and tattoos for Rebel MC (< this doubles as casual for Night Coven MC).
Romance: (by play order) Amelia is love, Amelia is life.
Katie would probably run to the hills if she even glimpsed the tiniest bit of my mind, don't mean I won't try tho'.
All the others, but since Amelia, Katie and Nina are the ones that stuck around they get dibs.
