True Bill COULD control Stan outside the shack, but it would be rather anti-climatic having him act as though he's going to use someone outside the shack, flashing through all these people, then just be like:

"Oh nevermind, i'll just wait until you go outside!"

That would be kinda lame.

Though admittedly, this was a cool theory.

it's one of the few theories that actually serve to explain the actual PURPOSE of the wheel.

and who know's? the twins still haven't really told Stan about Bill as far as we've seen, maybe Bill made a deal with Stan off-screen sometime after the events of Sock-opera?

Though by that logic, the next person to make a deal with Bill would be Ice Pack...

who is probably Wendy.... (for whatever reason.)
