This theory is ridiculous, the idea that THIS WHOLE TIME, the speaker had actually been working against us, is ridiculous. It legitimately just doesn't make sense.
I think there's always someone who wants a big twist in the this they play, so they try to make a tinfoil theory fact. Twists can be fun, but you gotta know when to stop.
When the idea of being the evil ones came up, I loved it, but that never came to pass so I let it go. The Speaker being was farfetched, but it was food for thought. The Speaker being the Consul is just too much!
