Legacies 2x13 "You Can't Save Them All"
I think the only person capable of stopping the dark!Josie is Lizzie, because for the Kai's plan worked she knew that she needed to separate the twins just like he did when she put the boys to hunt Alaric and probably also convinced Sebastian that the only way to keep Lizzie safe was by taking her away while manipulating Josie to trust him. Lizzie sure siphon part of the black magic of Josie in herself and so both will fight the burden of magic thus getting out of the prison world. And I hope that Hope is not the one to beat Kai, I feel that the twins should be the ones that ultimately defeat Kai after everything that happened with Jo and the destruction of the Gemini coven would feel like poetic justice.
