The writers must have been that desperate to give Dawn the win over Ursula. I mean c'mon, it's already ridiculous enough that Ursula never got to beat Dawn even for a single time, whereas Dawn lost to her other rivals at least once. On top of that, Dawn got a lucky break and she used that element of luck to her advantage to get that win over Ursula. Although I'm not content because of Ursula's loss, I'm glad that Pachirisu got a victory. That cute little guy really deserved something.
