I have a feeling that the flashback in this episode will continue where 516 left off, having Zelena get the Tinman's heart and the Lion's courage for her spell, but Dorothy will stop her, and that's when Zelena goes to the EF where she is in 3B. In present day, it will be Zelena VS Dorothy, Mulan, and Red, plus other stuff.
