Gotham
Bruce eyed Sakura in Clark's arms, and no words of comfort came to him. Their lives were full of danger. They would be until they decided to hang up their capes—and that wasn't something that he planned on doing anytime soon. Gotham came first. It always had. It probably still would even when he retired.
