I wasn't expecting Semak to get whacked so soon. I figured they would play it out a bit longer, eventually having Alex kill him, sending her into a tailspin of guilt. Well, all that went out the window when Ari pulled the trigger. The ending was kinda sad with Michael having to say goodbye to his son Max forever, who doesn't even know he is his father. Now, in the realm of stories, 'forever' usually means they will be reunited sooner than you think.
