Here is some food for thought, it’s a simple idea but, I keep coming back to it so I want to get opinions on it.

Let’s assume Mike Pencil is truly a traitor (looking very convincing right now).

When he receives his coin for certifying the fraud, he looks at it with some apparent confusion. He doesn't seem to realize what it is. If he is truly one of them, I believe he would know to conceal it. He was signaled to close his hand. Looks like a freemason logo.

He could have received a golden ticket to fool the DS. He could be acting on Twitter to stay in character.

Maybe not, maybe he is a traitor.
