When you go deep undercover, sometimes you lose yourself
Through intense concentration, Bill can temporarily phase his physical self into a small pocket realm contained within his passport. He cannot affect the real world while there, but is still able to perceive himself and his consciousness as existing, and may return to the location from which he vanished at any point (he will return automatically after a few minutes, as the pocket realm is unstable and cannot remain structurally sound much longer than that).
Spend an Action and Exert your Mind to phase yourself out for 3 minutes. You cannot perceive the outside world or take any Actions during this time, but nothing can interact with you in any way.
