That was a gutsy move by Malcolm, too bad it didn't work out. He writes the dude's name down and then convinces him to give him his idol! Freaking brilliant.
I can't believe he thought it would be a good idea to go and try and flip Dawn and Sherri when it should have been obvious that it was Dawn who spilled the beans on Corinne's plan (unless Corinne didn't tell Malcolm about that conversation), and that Sherri hates
Reynold and would never side with him.
So now Malcolm has the only idol in the game, and nobody else knows about it. He's still in a tough position, though. If he can win the next individual immunity he might be in a good position after that.
