Ok, I did a little googling on Smash the Mirror, because the title sounded familiar, and I was reminded that a song of the same title was part of Tommy (from the Who). In the musical, this is the point in the story (if you can call it a story, I was not totally impressed with Tommy personally) where the Mother smashes a large mirror that Tommy has been staring into, and as a result Tommy (who was psychosomatically deaf, dumb, and blind) suddenly recovers all of his senses.

Now, if you put Emma in the place of the "deaf, dumb, and blind" person, it could refer to her inability to control magic, which could mean that "Smash the Mirror" is the episode where she breaks through and learns to really control her magic, becoming a viable force in the ways of magic.

Anyway, that's just a random thought.
