Yeah I've heard rumours about how he was actually sent to the US by JE. Then I heard rumours about how he never actually went to the US and that JE was hiding him the whole time, because there were pictures of him in Japan when he was suppose to be in the US. Though, they are purely rumours.
If anything, Jin has definitely matured since he came back from the US. Hes still a jokester but even his taste in music seems to have changed (Love Juice anyone?). Though hes still really really good friends with Pi, so it must mean that hes still the same person as before, maybe just matured in thoughts and behaviour.
