i don’t think 47 has much character development. in contracts, 47 gets shot by someone who apparently recognized him and has some flashbacks, and in blood money he’s just a ruthless asshole without developing into one previously.
the only games where he got character development is silent assassin and absolution (say what you want about that game, but at least the writers freaking tried to give him character! (ABSOLUTION DID NOTHING WRONG)).
season 2 will hopefully fix that.
