A party of 'opposites' seemed just the place for a Wicked Witch, in Nessarose's opinion - even if said Wicked Witch was currently dressed up as a wheelchair-bound version of a certain Kansas farm girl.
She'd wanted to do away with the chair, but, unfortunately, she hadn't had time to look up the proper spells. ...And besides, without it, even with a 'walking' spell, she was far more likely to end up on the floor. It'd been the reason for her slightly-delayed arrival, though - NYC, though lovely, was hardly wheelchair-friendly, after all.
