SPOILER WARNING: This article contains major spoilers for Kieron Gillen and Jamie McKelvie's "The Wicked + The Divine" #20.
As it turns out, everything readers thought they knew about the night Laura died was wrong. In fact, she didn't die at all -- oh, and Baphomet never killed Inanna, either. In Kieron Gillen and Jamie McKelvie's "The Wicked + The Divine" #20, Laura tells Urdr exactly what went down the night she became Persephone.
While it's true that Baphomet fully intended to kill Inanna in order to steal his life force and buy more time on Earth, he never went through with it. Instead, the two had a heart-to-heart about godhood and living life to the fullest when they realized they were being played by Ananke. Inanna quickly divined where Ananke was, only to discover that she was at Laura's home in Brockley; when they arrived, they discovered Laura's fledgling divinity as well as Ananke's intent to kill her on the spot.
Thanks to some quick thinking, Inanna pushed Laura out of the way before Ananke could kill her. However, as all three recovered from the crash landing, Anakne took advantage and killed Inanna, stunning Baphomet. Before she could do the same thing to then, Baphomet took Laura down to the underworld with him to save her. However, the commotion caught the attention of Laura's parents, and Ananke killed them when they came outside to investigate.
Laura spent the next two months in the Underground with Baphomet, eating nothing but pomegranate salad (a reference to the Greek myth, where Persephone sucked on some pomegranates and was thereby sentenced to three months in the underworld). During her time there, she learned that Baphomet was, in fact, not Baphomet at all; in reality, he was Nergal, the Mesopotamian god of death, pestilence and plague and Lord of the Underworld. However, he was too embarassed to tell the other members of the Pantheon, because "it's instantly laughable -- they'd never stop mocking me."
At the end of her story, Laura invited Urdr to join them when they stormed Valhalla. Urdr flat-out refused and attempted to stop Laura, but in vain; Laura used Minerva's owl to project an image of herself to Urdr just before they put their plan in action.
