I hope I have the names right here...
When I watched it... it looked / sounded like Chloe was "told" to get off of Diamond. Diamond did yell "STOP!! STOP!!!" but, I think she was more or less trying to just get her to stop hitting her in the face, rather than giving up the match. BUT, Chloe should have stayed on her. She was definitely winning! Honestly, I don't know for sure why Chloe gave up at the end, other than I think it had something to do w/ her boob coming out, or maybe Diamond bit her boob or something, because when she started crying, she literally stopped everything... no defense, no covering up, nothing...
Honestly, I think Chloe should have won over all! Diamond may have won, but she got her ass kicked.
