Predictions?
I think he's going to be a bit more reserved, and likely hollow.
If you've ever seen someone who was not ready for jail life have to spend a month in jail and have their delusions rudely ripped from them, this seems like it is going to be a similar case. Call me optimistic, but I think we're going to see a more hollow, more drained out Chris Chan who is experiencing some of the consequences of his actions.
He may not think what he did was wrong, he may excuse what he did, but he has faced a month away from his legos, from the home he's known all his life, from Barb, from everything he's familiar with. Any smile he may of had when being arrested is likely gone. He may even have something of a thousand yard stare and just wants to get out whatever way possible.
Any sort of outburst might occur if he is told he needs to spend more time in jail, imo. The one thing he likely wants more than anything else right now is to get out and deal with the aftermath in a familiar surrounding.
I can see a lot of sighing, some complaining perhaps, but I think he's going to be more of a shell of himself, in all honesty
