I'm reading Red Hood/Arsenal, and at the end of issue #5 Jason goes back to Lucius Fox's centre, and he finds Bruce, but as an amnesiac. How did that happen? When did this series of events occur? Was it in the New 52, Rebirth? I'm so lost with the reboot stuff.
In Batman Vol 2 #40. Batman is supposedly killed when a warehouse collapses on him and Joker.
In #43 it is revealed that although Bruce had died, he'd come back to life. But the neural pathways in his brain had completely changed.
Kent wants to reveal to the new Bruce Wayne that he is Batman, but Alfred informs him he has lost all his knowledge from the past 15 years of his training.
