If you can explain this stoppage, you win a cookie

I don’t even understand what happened in this fight. I mean, I get that apparently these things happen in MMA, after watching a million fights, but this is just confusing. What the hell happened here? No one knows. No one. I would write more, but I think you should just go to about 10:15 on the video and watch and try to figure out the ending of this fight.
