Omg... that only means that Satoshi loses against Registeel, and against Brendan once again in a Regi-battle. Well, screw that part but the last title hurts... WTF Satoshi and Haruka Last battle... it either means one thing, either Satoshi goes, or Haruka.. and it's obvious the former can't leave the show, so... ;_; HARUKAAAAA.... nooooooooo... why the.... Who's replacing her then...

*IN DRAMATIC INDIAN SOAP FASHION*
:shinysuicune: : Nahi!!!!(NOOO!!!) NOT MAY/HARUKA!! PLEASE NOOO!! BOOO---HOOHOO!! Yeh Anyae Hai! (This not fair)
Hey, this means a new female charecter right? But Hikari is supposed to be in a new spin-off. Hmm......... "Dont forget Satoshi and Haruka's Adventures"....................... HOLY ****! No wonder! I mean currently May is IN the show so what else would they say in that line. Plus why only Haruka and not Masato and Takeshi. Hmm.... That means we were supposed to expect something special.......... a farewell perhaps.
Who noes? Maybe it just means that Ash loses to May in a contest battle and promises never to doubt her abilities again (he doent test/fight her anymore)

HAHAHAHA!
Anyway. I think you are right Shiny, we should'nt be pulling things out of thin air.
Maybe we were wrong about Hikari/Spin-Off, maybe not
For all we know it could be Ash, Tracey and Misty in Shinou!
