I researched the topic did Twilight Sparkle Actually Went Crazy in Lesson Zero with New Information. Twilight Sparkle never did go Crazy in Lesson Zero. But With Episodes like Lesson Zero under Twilight Sparkle Belt, you would swear She is Crazy and Insane as can be. This is a better version of this. I was shocked as can be. Felt like the episode intended to make her crazy as can be.
Hard to believe this is the truth I did this and found these results. Have done other research into the matter. Lesson Zero really did a number on Twilight Sparkle as a Character. Have heard Twilight Sparkle had a mental breakdown or something like that.
