Yes he called him an idiot or something like that but did not confront him at all. At least what we saw, And he was not angry he chose Jillian he was mad at the way he decided something so important. With a coin flip.
Joan buts in even when she has no clue as to what went wrong. She threatened to leave because baby went to the board room. Ron would be mad if Mike went home but would fight harder to stay himself. He would not give up.
Yeah ok but you're completely missing what is being said. Mike made a choice for himself, coin flip or not. Ron called him an "idiot", that's over-reacting.
Joan knew exactly what went wrong, she'd talked to Annie and they were watching it play out on the tv. Joan is very protective of Melissa, I don't see what's so wrong about that.
Ron wouldn't fight harder to stay in the competition, he'd be pissed the hell off and he'd try to get revenge on everyone who voted Mike out.
