IIRC from Dave's Misawa obituary, they had a very serious disagreement (possibly a fight?) in 96 or 97, and didn't speak after that. He was getting this from the foreigners in AJPW, who weren't privy to the details. I wish Japan had a shoot interview subculture like North America does, so we could hear some more details. Or if they do, more translators - I want the dirt!
