I think their chats about changing for good, choosing to be good, was a nod to the song, "For Good", from the play. "Who can say I've been changed for the better? Because I knew you, I have been changed for good.". (Of course in OUAT world, Zelena ended up choosing evil.)

Also, the water incident/melting incident was a total nod at Wicked. In the play Zelena "melts", but then we see she faked it.

Seems like the writers did a nice blending job, incorporating lots of elements of the Wizard of Oz interpretations.
