Sorry for the late comment, it's not a reflection of this complex chapter, but a casualty of several followed stories posted all at once. I read the chapter. I reread the last chapter. Then I read this again. So when Castle went back in time after the massacre and getting shot by Black, he was still shot. Does anyone but Black remember the massacre, Sergey?, Castle?, Meredith? How did Black go back in time? What happened in Black's life to make him hate himself so much? I'm kind of digging his "uniform".
