I am sorry guys asking that silly question, but I am re-watching whole thing, I am at season 6 ( not good season) and I have this question on my mind...in season 5 and 6 we see Jack's brother and father kills Palmer and Jack's dudes. But as I remember in season 7 ( I am not there yet on my re-watch) it was that private army guy. So who was it ? Jack's father or Private army owner ? Or did they worked together ? also what happened Jack's father ?
