"The Cutie Mark Chronicles" is the twenty-third episode of the first season of the animated television series My Little Pony: Friendship Is Magic.
On the way into town to find Rainbow Dash, they encounter the other five main characters and learn of their cutie mark stories (each told in flashbacks when they were younger fillies), much to Scootaloo's impatience: The Crusaders finally make it to Sugarcube Corner where Rainbow Dash is waiting for them.
The Sonic Rainboom unexpectedly allowed Rainbow Dash's friends to earn their cutie marks, and after they realize this, the Mane Six conclude that they are much closer than they all expected.
She further praised the episode as one that "boasts a surprisingly complex story (for kids TV) where all of the flashbacks tie together and reinforce the sense of destiny".
[1] Sherilyn Connelly of SF Weekly considered the episode as "one of Season 1's most complicated, carefully constructed stories, working with what we know about the characters and expanding their backstories while continuing to build the show's world".
