Hello everybody. Today I will make some predictions about the next episode. 

I predict that this episode will be like "Ocean Gem" from Steven Universe. A big epsiode to mark the halfway point of the season. And maybe it will start up an story arc for the rest of the season. I think that Starlight Glimmer might return... But, it will most likely involve Nightmare Star. The evil version of Celestia. I predict Tantabus will be the thing that caused Luna's transformation into Nightmare Moon. Even though the Nightmare Rarity arc of the comics disproves this theory. It is obvious that the comics arn't canon. I have a feeling the Mane 6 might lose in the end. 

That's my theory. Tell me yours in the comments
