I took it to mean there's an alliance called "The Spice Girls" in the game. If they're all girls then it has to be a mix of the girls left in this game. Excluding Elsa because Boo mentioned her separately.
On that note none of the girls are responding me which is worrying me. Though Lady Tremaine hasn't signed on yet. If I can get Gaston, Elsa and Lady to vote to evict Olaf then you'll be safe. So those are the people I'm focusing on.
