One thought came to me as I was reading through Julius Caesar. In Act 1, Scene 2, Cassius is suggesting a rebellion against Caesar, though through very veiled words, to Brutus, who is Caesar's close friend. In the dialogue, Cassius suggests that Brutus does not see, or is unwilling to see, what is in his heart, and suggests that he (Cassius) will be the mirror to show him what is in his heart.

Now, if they were to go full on Julius Caesar, I would put the plot as a conversation between Zelena and Regina, and Zelena is trying to convince Regina that taking out Emma would be in everyone's best interest, and that Regina has been avoiding that very thought due to her friendship with Emma.

In any event, I could see a very "Julius Caesar" moment between Emma and Regina occurring, though not as extreme as what the Bard actualy wrote (with Julius actually being killed by his close friend). which does bring to mind the robed person in Emma's vision, it could actually be Regina.
