I think Mike is upset with being blindsided and joins Ryan & Chrissy. They recruit Ben who is glad to rejoin fellow Hero Chrissy and has a relationship with Mike from Yawa 2.0 I also think Ben makes his Fake Idol and hides it under the log where he found his Clay Pot Idol Clue and nonchalantly leads Devon toward the log so he finds the Fake Idol to make Devon feel super safe being able to play an Idol if he feels something is up at Tribal Council.
Although I think they could go for Ashley who has done well in most of the individual challenges.
