Line all Dweeb jon now has an 'inner courage' (pathetic thoughts of revenge), and started to have crazy fantasies where all have in the en him laughting over a defeated/crying/apologizing Karyn/Sarah, but he not only have the fantasies he have also the rock in his hand with the promise to make all his fantasies real all he need to do is chose the right one.
But after the long run to his house Jon now have a cool head, should he wish to return back to normal? after all the change was made with de devise, not a wish, or he could FIRS wish his revenge in that case it would be a wish more in the lines of a modification of the devise in some way to make the girls wish they hadn't use it EVER or something.
after a careful consideration (few minutes)
"I know!! this is perfect, first I wish..."
