I have like 3 theories that I already shared in other threads but what the heck here I go again

-The race against time. Hades made a deal with them: They have a deadline to escape from the UW, otherwise their souls will belong to him. I say 3 days is most likely, because they have been filming during night time

-The villains (Peter Pan, Cruella, Cora, Blind Witch, James, Milah ...) are working for Hades, who ask them to keep the unvengers in the UW until the deadline expires. Hades offered them to go back to SB instead of the unvengers: a 1x1 trade: MilahxRumple, CruellaxEmma, JamesxCharming, Peter PanxHenry, Blind WithxRegina, CoraxSnow, etc...

-The villains are actually working against Hades and they are secretly helping the unvengers. After they help them to leave, all the villains are finally able to rest in peace because they solved their "unfinished bussines" and thus they will be freed from Hades' power (like Ingrid at this point)

-Zelena is Hades' daugther. "Jonathan" was Hades in disguise. That's why Zelena is so powerful. Powerful enough to cast the Time Travel spell, something never before done. And that's why Zelena was able to cheat death with her horcrux (pendant) without the Fate coming for her, like it did for Robin.

-Dr Whale will be at least mentioned at some point because he brought back his brother from death. Hades doesn't like when people mess up with death. He probably visited Dr Whale at some point.
