Shhhh you'll get my hopes up xD

Yeah but it actually does seem like a reasonable possibility (HOORAY!) Maybe Mombi will debut before this episode, in whatever episode has Zelena's arrival in the NEF, where their history is teased, then this episode will flash back to Oz sometime around 618 to show how they became enemies.

Or, better yet, they never were enemies, which is why Zelena was invited to the coven. Maybe we'll see something like Zelena and Stanum with Zelena and Mombi, but with Mombi being evil, too. I could see the flashback ending with Mombi betraying Zelena for something -- ruining her first time travel curse attempt? -- and saying something to the effect of "No hard feelings, right? Maybe we can work together again someday!"
