5. President Suvarov
One of the big reveals of the original run's end was that Russian president Yuri Suvarov, a key character in the show's fifth season, was the big baddie that Logan was working for, and that he personally sanctioned the murders of Omar Hassan and Renée Walker. The main reason that Jack is a fugitive to begin with is because of his attempt to put Suvarov down with a .556 rifle round to the head, so it seems only fair to either bring back Nick Jameson's big baddie or at least explain what happened to him. It's also entirely possible that Suvarov was removed from office following President Taylor's admission of guilt in covering up Suvarov's crimes, and it is also entirely possible that Suvarov's men are still hunting for Jack to try and shut him up. With this major reveal leaving holes wide open after the show's original run, it seems only fair to close these gaps and explain what happened with Russia in the last four years.
