There is a lot of time that passes between Twilight becoming the ruler of Equestria and the season finale. We get to see some things that have happened between then like:
-Pinkie gets a kid
- The cake twins run Sugarcube Corner
- Twilight becomes a Celestia recolor
- Big Mac becomes a father
...and some other things. But we don't know the BIG events. This is were the stained glass windows come in handy.
Let's just dive right in! So the first window has Sweetie Belle on it. The rest isn't in the frame, but I think we can safely assume it includes Applebloom and Scootaloo as well. The background looks like their cutie mark pattern. Maybe it's from when they got their cutie marks? But that doesn't seem too significant. If you have any ideas, please share!
The next window includes the young six defeating a rino in.... space?I don't know what else this could be.
The third one, I think, is the most interesting. It has adult Flurry Heart... at her corination? Saving the Crystal Kindom from an outside force? Rejuvenating the Crystal Heart? It could be many things, but we see the castle spires, the crystal background and the Crystal Heart.
Please share your thoughts or any other background details from the episode, The Last Problem.
