If Philora, Mulan and Robin are in it, could it be about hunting Maleficent (in a flashback)? We know that Robin crossed Maleficent with Will in OUAT in Wonderland.
I like the idea of everyone going back to FTL and Regina being the witch who is being hunted because of the curse. Will Snow, Charming, Emma and Gold have to save her? Will they want to? Will Henry beg them to save her like he did in Season 2?
