ok it should bring him back as the jack without the mask and not evil he'll just be some bum on like the streets you think is crazy and he helps you and in the end you find out he was some crazy guy form 500 years ago but doesnt look different because hes a cool basterd so he lived !
what i mean is like i want jack to return but not as an evil guy but as like a bum that saves your life or something then you end up killing him because you want to lol
