Even when a person hates a thing and wants it gone, any significant presence in someone's life can create a hole that needs to be healed when it's gone. This is the werewolf experience in action (leaning on the traditional werewolf who attacks everyone they're passionate about, regardless if the feeling is positive or negative). The force of that experience, so pervasive, will definitely leave a place that wants filling. And it's already clear that Calliope might not have the relationship skills she needs to manage herself without that extra balance she's had to get used to.

It's like someone with a crooked leg who's had to walk with a cane for years. They get a correction, but they want to keep using the cane because it's an old friend, even though they no longer need it and feel completely off balance with its assistance now.
