Shes ready to do some wedding planning, but theyre interrupted even more.
Regina calls in the troops after finding out what happened with Zelena.
Thats when Hook reveals his half-wand, which was once used to expel the Black Fairy.
They need to find the other part, but Zelena doesnt havetime,guys.
Thats all well and good, but Blue is still in a coma.
Rumple leaves to make a run at remedy the situation, and Zelena shows up.
She asks if Belle can watch Robin, and shes happy to.
Its not like Belle has been busy being a badass lately.
Zelena is determined to be one, though.
She sets off to end the Black Fairy, once and for all.
In Storybrooke, David goes investigating and stumbles upon Henry, who is deep in the writing mode.
Making no progress, hes turned to those crazy drawings he did before.
Meanwhile, Regina stops by to see Belle and realizes shes watching after Robin.
She immediately puts the pieces together, but Zelena is well on her way to fight the Black Fairy.
Thats when we flash back again to Zelena in Oz.
A man shows up who says he needs help, and there he is the Tin Man.
But shes not interested in helping without something in return.
Back in Storybrooke, Zelena is in the mines when Regina chases her down.
They argue, which leads Regina to ask why Zelena insists on proving shes better than everyone else.
Zelena insists its because she is, and shes going to stop the Black Fairy on her own.
We flash back, and Zelena is traipsing through the woods with the Tin Man.
They dive in to Zelenas past and how her mother abandoned her.
Suddenly, a lion comes and snags the Tin Man, and Zelena hops into action.
Onlyshehurts people in these woods.
She throws Regina against a wall and puts Gideon over her to keep watch, but Zelena isnt done.
She wants the Black Fairy dealt withtoday.
In town, Snow is still really dead set on wedding planning.
Impulsive as ever, she goes deeper and deeper and finally throws the Black Fairy against the wall.
She redirects Zelenas magic to weaponize the crystals.
But Tin Man is continuing to run out of time.
She points the crystal (presumably to the western sky) and looks to head back to Oz.
He finally turns to tin, and Zelena leaves him behind.
She didnt go back to Oz; shes ready to come back and fight with the heroes.
And man does that fight come with a price.
She can ultimately stop the Black Fairys use of her magic… by destroying her own magic.
Looking at it from across the table, she realizes shes alone.
But when we flash to the present, shes joined by Emma and Regina.
She opens up the heart and makes Regina promise that if something happens, shell watch after Robin.
