Rainbow Rocks

So I watched Equestria Girls: Rainbow Rocks today. I enjoyed It, but as is always the case for me with MLP, it raised some questions but answered others. First of all, where has Sunset been living? I'm pretty sure she is homeless, so where is she spending her nights? Moving on, we now know why Starswirl made the mirror. He made it to get rid of the Sirens. Also, we see Twilight doing her thing with the portal and that's just awesome. My final thought is that it is the ABSOLUTE BEST THING EVER to see Human-verse Twilight.
