There is a summary on serebii forums, and Barry will say to Ash that he got Volkner's badge, strange. maybe he already got his last badge?
I smell a writers brain freeze here. How are they gonna explain the fact that Volkner is depressed if Barry just beat him ? Volkner isn't depressed because an opponent beats him, he's supposed to be depressed because he just defeats opponents without any real effort. Seems fishy to me...
