OK let me break it down:
Zig and Ogre are obviously the only two innocents left. CL would be the one turned as I'm confident that Zig is Hypo as he claimed. We can ask them which one of them was Hypo. Though they cannot tell us who they turned, Zig was voting for CL so it makes sense that he would vial him. You and Ice cannot be innocents. Capiche?
How many ES are you assuming? I KNOW you're one off. Capiche very well.
