Batman/TMNT #4 (2015-2016)

With the possibility existing that they might never get home, the Turtles take up residence at Wayne Manor. Everyone seems to be adapting except for Raphael, who still can't understand why his friends all trust this Bat-person. So Batman takes the skeptical Turtle on a trip down Crime Alley to tell Raph what led him to don the cape and cowl in the first place. Co-published with IDW.
