Nope, we didn't get a new opening. Probably next episode.
Silly Iris, fighting a Garchomp with your little Axew. That monster can actually fly, you know. Also, blasphemy! There's no way Axew could NOT have done damage. He probably did 1 HP with Scratch...but nothing with fixed damage Dragon Rage? Yet another reason Cynthia's Garchomp is broken.
Really nice to hear Dawn is returning for a while. I always liked the 4-team group format back in the Hoenn saga.
