It's Flannery's first official Gym Battle!  And Ash's.... many-eth...  I've lost track of which one he's on, but he's making good time here in the Hoenn Region and having an interesting match against Flannery.  Maybe underestimating her a little?  Maybe using some brilliant strategy at other times?  You be the judge, but one thing's for sure, these two are an even match.
