While Brayko's line referring to Thorton as the "(expletive) offspring of Ronald Reagan and the (expletive) American Ninja" is always funny, it makes more sense that he'd say something like that when you remember that he is after all, a fan of American 80's pop-culture.
Scarlet Lake, intrepid photojournalist. Willing to run as many stories exposing major Halbech scandals as you can email to her. But given that you are personally acquainted with just how extreme Halbech's overkill can get when trying to hush up one scandal, how on Earth is she living long enough to publish all of them? Well, it probably helps that journalist is only her day job, and her night job is "master assassin". Also in that Halbech needs her to live long enough to at least finish the Taipei assassination they hired her for.
In Taipei, who's the one who sent you the faulty information about who's trying to assassinate Sung? The Triads. But where are they getting THEIR information from? Steven Heck. Note that Leland knows about Steven Heck even though Heck is not listed as an agent on any payroll. It's entirely likely that Heck was hired by Halbech to sow misinformation during the Taipei mission to let the real assassin run free. There's even been a Shrug of God about this.
Heck even says that he thought Michael knew Scarlet was the assassin, and just wanted to boink her in spite of it. "I thought it was pretty classy of you." Hehe.
