Just watched Mastermind and I can see Glacia coming in Lucifer's stead and when Satan starts talking shit, Glacia is getting pissed at him insulting her man (due to not knowing the timeline, I'd probably keep their relationship ambiguous as to whether or not, they're dating or not, but Glacia would be upset) and Bee having to stop her from intervening lest she get herself killed/maimed by him (she's a powerful sinner but still a sinner none the less).
(I wrote a Helluva Boss fic with Glacia's sister, Willow, that's posted from a writer named @CasonArtSweet but I'm very slow in updating it like still in season 1, slow.)
