Applejack: You were there, Twilight...you met her...is all of that true?



Spike: Why do we always feel the obligation to answer to everything Cracked says?



Twilight Sparkle: Yes...sadly, Applejack, it's all true. Fallout Equestria really was like that. When I was ready to leave it, I told Littlepip that allowing the younger Rainbow Dash to do her first Sonic rainboom would erase her...Littlepip....from existance. And you know what?



Applejack: What?



Twilight Sparkle: She was happy about it. She wanted her existance to be erased. There's a reason why Fallout Equestria is what convinced Starlight Glimmer to stop screwing around with time and let the Sonic Rainboom happen. And Cracked just told you the reason.
