Or, what would've happened if Uma was one of the 5 VKs originally selected to come to Auradon. And if Hades hadn't been able to wake Audrey up... and that scene was a reprise of One Kiss instead.
(Also go read Were You Expecting Flowers? first because it's a prequel to this :))
This is just pre-D1 Hades stuff and then setup for an Umaudrey thing
(Btw although this is tagged as Hades x Maleficent and Hades x Ursula, both are pretty minor and only in the first chapter. It does mean that Mal and Uma are half-sisters tho. Also there's no actual Audrey/Uma so tags are a bit misleading, sorry)
