Four wonderful things from S6 Ep 1&2 (spoilers below)

1. Starlight Glimmer not only learning from Twilight, but living with her. Also I love her new Mane style. Loving that she is also in the intro picture, shows some permanence.

2. Adorable Flurry Heart. Nuff said, thank goodness it wasn't Skyla.

3. The most awesome thing ever. Canon that Celestia and Luna were not born Alicorns. This further leads on that Twilight and Cadences lifespans will be on par with Celestia and Luna's. Since we have someone working on the show stating that Twilight will not outlive her friends, the theory that they are the living embodiment's of harmony, infused with the Elements power at the end of S4, thus extending their lifespans as well seems all the more plausible.

4. No Sombra.
