YMMV / My Little Pony: Friendship Is Magic S1 E23 "The Cutie Mark Chronicles"

• Alternative Character Interpretation: Between Pinkie Pie's flashback including a in-universe Breaking the Fourth Wall, ending with "And that's how Equestria was made!", and Pinkie being Pinkie, a common fanon is that her account is less than accurate. Not helping is that it failed to mention her favorite sister.
• Captain Obvious Reveal: The explosion that caused each girl to get their cutie mark. It's obviously a sonic rainboom, and it's obviously the same thing in every story.
• Fanfic Fuel: The backstory revealed here makes it quite easy to do AU fics in which Rainbow Dash not doing the sonic rainboom results in a radically different setting, and gives credence to the idea that an OC or a pre-existing character was influenced by the sonic rainboom too.
  • As of Season 5 the show has done the first of those.
• Heartwarming in Hindsight: Rainbow Dash defending Fluttershy is already sweet considering their close friendship as adults, but in Hurricane Fluttershy we see Fluttershy was bullied pretty bad and it still haunts her, so Rainbow Dash coming to her aid becomes even more awesome.
