I gave Steve and Bucky rules when they joined the war. There were only two, but Bucky managed to break both of them and Steve managed the break one.
Rule #1: Don't get captured.
Rule #2: Don't die.
I guess, technically, they didn't break Rule #2, but I was told Bucky died, and later I learned that Steve had died too, but neither of them was actually dead, so I could let that one slide.
When I woke up in the twenty-first century, Steve told me the war was over. But, of course, world peace is a myth.
You've been struggling for the last three years to survive, stealing to eat. You five rules; Only steal from the wealthy, always stay somewhere new, be honestly when you can, never steal more then you need, and never get attached.
You luck went dry, and then you stole from the wrong guy. Now his friend and colleague (Bucky Barnes) won't stop till he finds you.
