Yeah, he hasn’t that’s the thing. He was pretty open about his plans in 519–he flat out told he wanted to leave all the heroes in the Underworld and go to SB, just them and the baby. Zelena has a case of heart-eyes that is making her forget that or something.
Zelena assumed that Hades had a change of heart like everybody else was led to believe. Zelena was adamant about not leaving her sister behind, but Hades hid from her that he still wanted to leave them all behind.
And unless he still has some intent on using her baby to activate the time travel curse….this could really place Zelena into a position to kill Hades herself if Emma convinces her his real intent, maybe that’s what on the fairy tale pages?
