Wasn't that basically the same thing that happened after Knightfal? The Bat recoups and then regains his edge with Shiva before going back to restore the order that Azreal threw out of wack? This seems to follow the same principle only it is Cat who is helping him heal and regain his edge, the fact that they get back together is really a bonus (to me at least since i can't speak for everyone). Then again given the level of vitriol i am seeing from the readers i can tell they would not be expected to care for any of that since the consensus i am seeing is that King has utterly ruined the characters for them.
