Midnight Sparkle’s Return  
Part 2/2:
 
Twilight gasped and cringed with fear over the mere sight of Midnight Sparkle in her mind again.
 
Midnight: You and your little friends thought you had defeated me for good, but I will always live in your distant memories. You can never escape your past. And now I’m back to take control once again.
 
Midnight then transformed herself into her demon form, but what she never considered was Twilight gaining a whole lot of weight. So, after she had reformed…
 
Midnight: (scream) Wha- What the hell?! Where has all this.. this… fat come from?!
 
Suddenly, Daydream Shimmer appears from behind.
 
Daydream: Yeah, a little tip to remember: never control a fat body. Twilight’s been this size for months and she’s not going to be thinner for a long time.
 
Midnight, not wanting to control magic with a massive flabby body, gave up. She then snapped her fingers and disintegrated into ashes. Daydream smiled warmly.
 
Daydream: Don’t worry, Twilight. She won’t bother you ever again. I guess there is some good from being fat after all.
 
Both Twilight and Sunset smiled and slept peacefully for the rest of the night.
