It was awesome to see Articuno here. Being that it is a wild legendary, even though considered a friend of Noland, it was interesting to have it obey Noland's commands. But Noland treating Articuno's injured wing made trust him more. They also enjoy plane races and training. Ash choosing Articuno to battle may seem out of his league, but his reasoning for that was to give himself a challenge to test his skills against strong trainers and Pokémon, especially a legendary, like Articuno. And great to see Charizard again at the end.
Scott, you crazy driver! It's not safe to drive like that, but this is the anime, so whatever.
