Brolisten to this theory that i picked up from comment section. Someone mentioned that DG aka James lee is the body alternative of charles choi because when the past is always shown either someone is sleeping or someone else is awake and i agree to that. Even in here when James lee came to stop union battle the message of chairman was relayed by her daughter rather than charles choi himself.Even while talking with eugene charlea choi repeats the same lines that DG aka James lee says that " He's too old". Hehe just a fun theory that's it
