Me: DON'T DO IT!!!
Me: You must not have read "Cupcakes".
*I hand twilight the book and she reads it*
Twilight: WHY WOULD SHE DO THAT TO HER!?
Me: I wish I knew.
I kinda like Alicorn Twilight but I also don't like it. Twilight basically spent the series learning about friendship and now she's in a position where, even if the status difference is ignored (and it probably will be in her social circle, her friends won't allow for her to ditch them, especially if someone else is pressuring her) she'll eventually have to watch them die. The only saving grace in the problem is Spike - as a dragon, he'll live for a long time. In fact, before Alicorn!Twilight appeared, there were fics shown an older Spike remembering the Mane Six after they had died.
However, I do like Alicorn!Twilight and hope that there is a new season exploring how she learns to deal with her new status. Flying lessons with Rainbow Dash, maybe?
