Has anyone been thinking that the guy at the end may be Kyoko's dad? I have! That would be...

really? i would think it would be pointlessly confusing, considering Kyoko has already stated she doesn't have a father. How would he know that Mogami Kyoko lived there, or even care? If he had abandoned his wife and daughter and not died as has been implied, why would he randomly want to hunt down where his teenage daughter lived? He wouldn't even know what she looked like. Hell, her own mother probably can't recognize her right now. Besides, that's not the face of a 30-40 something year old man. If that's not sho, i will be very surprised indeed.
