I kept quite on this thread for some time now. Reason being is that i have to repeat myself. My opinions are already expressed in my previous posts.
Oh yeah. That picture that you found there, Unknown Man? It's fake. Sorry to burst your bubble, but it's just not real. Just ask the people who actually watch the minute details of the show. (I'm not one of them) I know this because of a previous post. From what I can tell, either the picture actually did happen (but not because they were about to kiss. It's a kids show, for cryin' out loud!) or somebody edited the picture.
Even with that picture, it does seem like Ash is showing more feeling towards May than Misty. As hard as it is for me to say that, it's true. Although, the only reason that I see that is because May either gets in trouble a lot, or argues with Ash. And boy does May get in trouble. (much more often than Misty)
Whether you determine that Ash is looking more at love than his 'Master Quest', the most likely girl that Ash would go out is none. He's absolutely hooked on trying to be recognized as the best Pok?mon Trainer in the world, he's blocked out nearly everything else. Besides, the series could change dramtically should Ash fall for a girl.
