God I loved this episode. I'm defiantly going to watch this episode mulitple times lol.
The thing I loved most was that it showed how strong Jessie was. Haze+Sonic Boom and Sonic Boom+Poison Tail was incredible and IMO the same as if not better than Dawn/Ursala/Zoey/Kenny/etc standard. The only reason she lost is because Seviper/Yanmega are just weak pokemon. If Jessie can make her pokemon physicaly stronger(shes got the appeal down) she could be an enormous threat.
