Continuation of Does Deadpool know he is breaking the 4th wall?
So Deadpool knows he's fictional. But how does he know things like what issue he's in, or where the fourth wall is so he can talk to us, or if speech bubbles are working properly.
For example, even if I knew that this was all a holodeck simulation in which Captain Picard, Riker, and the rest of the crew are role playing actors on a popular TV show from the 20th century, that wouldn't allow me to detect when I'm paused, or how long the simulation has been running.
How does Deadpool know these things? We know where his immortality came from. Where did his fourth wall ability come from (beyond just discovering he's fictional)?
