This "kid" reminds me a lot of how Charles Manson acted in court. In the beginning and for a number of years after the trial, Manson was all "smiles". Not anymore he's not. Guess when it sunk in that this wasn't a game, so did his facial expressions.
But the years will take their toll and we will see it in the age progressive mug shots like we see of Manson's. Say 40 and 50 years from now, this kid's face will be transformed into that of a hard core inmate with nothing left to smile about, perhaps when he realizes that he's outliving everyone on the outside...if he lives that long.
