Jack had many partners over the years, but none had so pointless a death as Curtis Manning. In season 6, Curtis was once again serving at Jacks side, but he was also forced to work with Hamri Al-Assad, the man who was responsible for killing Curtis men during Desert Storm. When Curtis learned that President Wayne Palmer had granted Assad a pardon in exchange for his help in stopping the terrorists, Curtis felt Assad didnt deserve to get away with what hed done. Attempting to kill Assad, Curtis was gunned down by Jack, who had promised Palmer that he would protect Assad. It was heart-wrenching to watch Jack kill another ally, and youd think that it would have affected Jack for the rest of the season...but it didnt. Minutes later, the nuclear bomb went off, prompting Jack back into action. Aside from a couple small remarks, Curtis wasnt mentioned again, and his death amounted to nothing. You want to kill a character on the show, fine, but Curtis deserved a better death than that, and more importantly he didnt deserve to be forgotten afterwards.
