Ret didn't hammer Danner yesterday, even though he had the chance. So if Danner flips town, I strongly suspect Ret to be town aswell.
The same thing applies the other way around. Maybe he didn't hammer because he wanted to save a scum teammate? That itself is not enough, but paired with his defense of Danner today, and what I thought was a 'forced discussion' yesterday, I suspect them to be on the same team.
