we have to understand that Q word the one shirt two shirt thing the way he did for a reason. it clearly isn't clearly saying one in and two out or visa versa. it must be confusing for a reason. if Q wants to clear this up, Q will absolutely do so. the only other outcome will be BOTH happening. maybe this is intentional.
people wearing their Q shirts outside will not be at risk inside and people wearing their Q shirt inside will not have been identified and called in from outside. best of both world?
