On the other hand, Twilight rightly felt that she had nothing to prove, and thus didn't want to sink to Trixie's level; "two wrongs don't make a right", after all. Still, she did learn that if you're using your powers where and when it counts, and not just to boast, then it isn't sinking to the other pony's level, or otherwise showing off, and your friends will (likely) be grateful for it. In any case, her heart was in the right place, but I'm guessing Twilight was otherwise a little confused at first about what "showing off" really meant.

Overall, I was a little worried that this episode was going to subvert the aforementioned moral for the sake of comedy. I was kind of relieved it didn't. After all, even comedy has to be serious sometimes.
Cartoons aren't "just for kids"...but they're not just for adults either. They're for everyone.
