Nightwing trained well
In this issue Nightwing is affected by the Scarecrows fear toxin, this makes him hallucinate that he is surrounded by many of his and Batmans worst enemies. He fights through them just to get to the man who is trying to kill Carol. Flat out, this is wall to wall action. Yet the underlying messgae here is that Bruce Wayne trained Dick Grayson to have a very clear and disciplined mind.
This is just an incredible issue with a very unsurprising surprise twist. Hpwever it does make for a good advertisement for the next issue.
