The first thing Carissa does in the morning is prepare spells; the second is track down Asmodia, who she'd meant to meet with the previous night to coordinate stories on Hell, before things happened. She should probably expect that things will always happen. Asmodia has her authorized lies, but it felt yesterday like that wasn't quite enough, and the obvious explanation is that it's related to the thing where Asmodia had a message for Carissa from a dead devil.
Which in hindsight maybe she should have asked to hear, or at least flagged as awfully important.
"What happened in Hell? - not to you, I don't care if you want to relive that or not, but, uh, around you."
