Mark & Josh were playing pool and had a bet that the loser has to drink pickle juice with hot sauce. Josh scratched on the 8 ball and wouldn't admit to losing but wanted Mark to make good on the bet and drink the pickle juice anyway. While he was preparing the drink, Elena jokingly told Mark to throw it at him which she recanted but Mark was set on doing it and of course it did not go over well at all. Then Josh poured ketchup and ranch dressing on Mark and Mark seemed to legit think this would turn into a fun food fight thing but he was way way off. Josh was furious and would not accept Mark's apology. Then Josh went on to flip out about everything and anything while standing in the hot tub. He wasn't making much sense and every statement he made, he said about 100 times (love and respect, my family is watching this, you disrespected me, and so on). Mark is now Josh's #1 target to get out of the house. Mark mostly stood there and apologized again for the hot sauce. He tried to ask Josh a question but he was talking in circles and never answered. He was too heated. [on this Josh was 100% wrong about the game and the bet, but Mark was sooo far out of line about the pickle juice plus the hot sauce burned his eyes]
Then Dom wanted to talk to Christmas - which Christmas would only do with a witness. Dom wanted to know why Christmas turned on her and Christmas said you were throwing my name around the house while I was in the hospital, any time I tried to ask you about it you wouldn't answer. There was a little more but lost brain cells and all.
Then Jessica started with Josh because when he was yelling at Mark he said he hasn't lied in the game but she pointed out that he told her he would vote out Christmas but he said that wasn't a lie because he was loyal to Christmas and I didn't say I was loyal to Jiliian, she's a nice girl and I love her and respect her but I was loyal to Christmas. (makes perfect sense, right?) Then he went on about telling her to stop trying to come back to the group and play the game because she'll be leaving soon. blah blah blah. He stood up yelling at her. Kevin later said that made him look so so bad - first to be yelling at a woman like that then to stand up in an aggressive manner.
(I don't like Josh at all so I admit to bias against him.)
This went on for a couple of hours.
