Late reply from me. I was waiting for the episode where I can fully understand to arrive, but it's delayed.
Anyway, Shooti is still okay to me so far. Like many others have said, his design is similar to Paul's and a bit distant. However, he does explain to Ash his strengths and weaknesses during and after the battle and questions Ash if he's truly ready to battle from what happened the 1st time. Not very snobbish but very social compared to Gary (1st season) and Paul.
As for Ash, he was more reckless this episode and this reminds me of that Ash VS Takuto where he wasn't able to battle or reveal all of his opponent's monsters. Oshawott could have tried defending with Shell Blade, Tepig should not have been the next monster in line even though it probably couldn't take out Shooti's Janobi, and Snivy should have done continual Leaf Storms. Unsure if Eccentric/Perversity is her ability though. At least Ash didn't have Mamepoto use Quick Attack on the Water/Ghost but at least escape Water Pulse with it. Yes, Ash was in over his head this episode.
The multiple Don Georges was unexpected to me. Since I know there are multiple Battle Clubs in Unova Region I should have expected this. What I thought was that Don George's disciples would run each club instead of his siblings. Like with Nurse Joy and Officer Jenny, how would a reverse gender of Don George look like?
This episode was OK. I feel Shooti could be a bit of a mentor-type rival yet helps him indirectly.
