Yes! She could be a bit shady. After all, she was referred to as a beast by Morraine … taking a different form, perhaps? And … she told Bae she was on the “right” side … not “good” as everyone assumes …
I don’t hear Morraine call her a “beast”…Morraine says she’s an “ancient being that rules the night…the original power”. I’m not sure what BF’s intentions are, but she did tell Bae that there was “good magic and bad magic” and she was on the right side..which is probably “good” magic.
