Where is the other Starlight Glimmer?!

So in Mirror Magic, Starlight came to the human world. But how come we have never seen the human Starlight. I have my suspicions about one of the Dazzlings but I am probably wrong

Since we never officially saw Starlight's human twin, my guess is she's probably in the same place as Sunset's unseen human twin. My headcanon is that Human Sunset transferred from Canterlot High to a school located in a different city before Pony Sunset (the one we've actually seen) moved to the Human World and Human Starlight is also a student of the school that Human Sunset transferred over to.

The human Starlight would have to be an adventurous person and rarely in town.
