hmmm... thats some awesome bickering there....
anyway...

Heres one for you. If i remember correctly, Sora's FATHER in particular was never mentioned. (unless you want to count Riku saying "we may never see our parents again..etc", but that would only be a natural thing to say if you had both your parents and the person you were talking to's dad had run off)

In any account, In Deep Dive, the scene with the glowing eyed Uknown and the Sitting Uknown in front of the ocean, where the sitting unknown says "He looks just like you" to the G.E. Unknown....That seems quite like something someone would say when talking to a parent about their kid. And considering that G.E.U. hasn't been referenced as the same person as BHK/Dual Wielding Uknown (as far as i've heard, and BHK seems to be the only one that such a statement about sora could be made to.), I wonder if we're looking at Sora's Pappy in a big black trenchcoat. hmmm....
