Puppet Rarity

Your probably confused, yes discord is the puppet, but so is rarity IT MAKES SENSE! So after Sweetie and the others were murdered, Rarity was accused of the tragic incident, she went to her friends for mental help, but even them thought she was responsible for the act, Rarity slowly went insane, she wanted to "fly away" so she jumped off a roof, the doctors couldn't help her, she was put into a coma. after being in a coma for 7 months she was stabbed to death by Applejack, who still thought that she had killed her precious apple bloom. Rarity now haunts the pizza place as the soul of the discord puppet, unable to see her sweetie ever again, she kills any pony she see's with a bagde, music being the only thing to calm the poor mare.
