And she walks, with the Unseen Servants holding up the hem of her dress and no other concessions to the landscape, through the streets of Dis, unafraid, determined, winding her way across red-hot metal bridges towards the palace. She has activated the pin of Glibness, by now, but it's not mainly Bluff she's leaning on. This is Asmodeus's, and she has been commanded to go to him without thought of other choices, and to remember that she is not Irori, and so here she is, where Irori would never go, to give herself over to Asmodeus; He alone can win a contest among the gods simply by ordering it won for Him.
She is afraid, but not very afraid. Smarter Carissa had a plan.
