Morisaki's belt
After a few minutes of thinking about it I went back and checked why the two at the end gave Mike their belt's. The old man (Brazil) was there to see Morisaki (Japan) fight Mercado (Brazil) so therefor since Mike beat Mercado, he gave him the red belt. I don't understand why Morisaki gave Mike his belt, since he was there to fight Mercado, it doesn't prove anything that Mike beat him. I guess it was a heat of the moment honor thing? Even though he doesn't know him, or have any idea why they were fighting.
By the way, Collins committing suicide was weaaaaaaaaak! He leaves his wife behind like that. He would have known Mike didn't want him to do that. Not only could he have refused to press charges, but that so called "evidence" isn't evidence at all. What are they gonna do, get a dirty cop to say he collected the evidence and waited weeks to file a report? It's illegal and ludicrous. Mike commits suicide completely voiding their case anyway, and did they follow through with their demands? Very short open-ended ending. Would have liked to see it run 3 hours instead :P
