I think Bob's whole life has been a game. To see what he can get away with, to cause his family as much grief as possible, and above all to prove how much more clever he is than the rest of us mere mortals. And yet, clearly, there's enough self-doubt and self-loathing to manifest a deep-seated need to get caught. To finally be made to pay will probably come as a huge psychological release. I keep going back to that fucked up story of Seymour showing little Bob his mother about to plunge to her death, and how everything that followed was set in motion in that moment. [/snap analysis]
