I don't think he was 'running the show' personally, I saw it more that he was trying to continue the party from the previous night, and of course he would want that! My opinion was that he wanted more naked girl massages and was trying to get the party started, get the girls drinking and the games playing so that he could suck some more fingers
By the way, in PM Yury translated Nora and Irma's conversation when they got back to B1. They didn't like the atmosphere, and Nora said "I know what will happen now we have left, Jess will hang out with Alex and the other girls will sit on their own in their corners" and she was exactly right!
