I'm guessing... hell, I'm gonna take another stab in the dark and predict that Roy is gonna be in deep shit somewhere in the forseeable future.

Love the man but will eventually mess up, and gets his ass handed to him on a platter, and Ed will have to clean up the mess. But the question is how Roy gonna screw up. Trsuting the wrong people (highly unlikely), or voluntarily getting himself into the shit to protect others (highly likely)... mind you, all of this will have to happen after the Ed angst.
