Rob is going home! He's going to his own home, in fact, after refusing to move in with his parents because he wants to remain independent. In the end, his leg had to be amputated to mid-thigh, but I don't know what they will mean as far as artificial limbs. The main thing is he's out of physical danger, and remains determined to be a positive contributer to his family and society. That's a pretty darn good attitude to have.
