I'll Do It!

"I'm the closest I've ever been to getting my brother back and I'm willing to do whatever it takes," he writes. "If you do anything to compromise his safety or screw us over, I will help the A.M. track you down and lock you up for the rest of your days." He adds: "You know this isn't going to stop at one return favor, right? You'll owe me for a long time".
