Twilight! NO! *breaks down sobbing*
No! This cannot happen! No! Ok, stay calm. "There is always light before the dawn," remember? Giving in to fury makes her stronger.
Angry Pie, I know you want to protect your foals, but you miss the whole point of the Element of Laughter. I have been bullied, teased and picked on every since I was old enough to realize it, however, I have never forgotten how to laugh. Laughter is more than just the physical act of laughing. Laughter is joy and love, the way that people can make it through this cruel world, without becoming cruel themselves. Yes, Laughter can be corrupted, used as a from of hatred, but isn't it the same for every Element? One part does not make up a whole.
Apple Pie understands this. Why can't you?
*climbs off soapbox*
I also have a theory about Twilight's voice. She never went through a nightmare like arc. Maybe this is her repressed nightmare side? If so, Celestia help us all.
Discord will not win. I will not rage at him any longer, for that is what he wants.
I think I'll just curl up in the corner and sob for a while. I need to mourn. Great story!
