I wonder if Amara, weeping near the well, her teardrops falling into the water would be a way to return the water to Nyx. I could picture Cyrus being mortally wounded near the well, Amara weeps, a teardrop falls into the well. Nyx rises from the well, the brothers are released from their bottles. Cyrus is healed.
I really hope Amara taught Jafar that he needed to steal waters from the well in order to enact his spell. I’d love to see Nyx curse Jafar.
I got the impression that Ms. Jabber wonky (I love that auto correct) was beginning to dislike Jafar using her but not giving her any credit.
Also, I wonder if, in the case of Philora, if the water is still accessible from the well. The opening of the well seems to be covered. But can they remove the cover to reveal the water? Why have they covered the well? To trap the wraith? To hide the healing waters? Possibly the only way for Phillip to keep his soul is to drink the waters often.
