Not sure but ...
According to the feed watchers we are being given a very highly edited view of what is happening in the house to make us think one way, different from what is happening. We may not have seen some things that would explain it. It was also shown that Zae used a slur in the house outside while playing game with Keanu. Others were around, perhaps it became a bigger issue. I'm thinking Rylie is playing the goofy cowboy but perhaps his brain is really working strategy. At this point maybe it was just get some brawn out before the physical games start. Or maybe he is in an alliance with some gals, using his guy alliance for info. They are reporting there are LOTS of alliances, many contradict. They said Vince and Jimmy are in a final two and based on their behavior some are guessing they know each other, well.
Not sad he left.
