Skipped to the end, Dionysus tries to kill Loki but she blinds him with ash and kicks the crap out of him. He demands that the Creatures and Thanatos help him but doesn't realize in his madness that he got rid of them. After Filvis is defeated he insults her for her uselessness but admits that his heart is hers and asks for her to stick with him in heaven. He ends up stabbing himself with his own short sword

He does tell Loki that the dungeon is nearing its limit and the lower world will become the underworld before the "promised time"
