Heartwarming / Parting Words

• When Celestia goes to apologize to Twilight, she reveals that, for all her power, she's just another pony, and as such is not infallible. She then talks about how Twilight and her friends were able to accomplish so many things together, and how they made her so proud. The whole scene culminates in this little exchange:
  Twilight: Why did you keep giving us... giving us such dangerous assignments? The dragon, Discord, the Crystal Empire...? Why did you pin so much on us?
  Celestia: Because, my dear Twilight, you had gotten into something of a habit of exceeding my expectations.
  Then Twilight did run across the room and bury her face in Celestia's mane.
