Nightwing Returns

Dick Grayson gave up being a vigilante when Jason died, yet finds himself drawn back into things when the darkness finds its way home in a manner he didn't expect.

Disclaimer - I don't own Batman vs. Superman, which is the action movie I choose to write a pin off for. I also used elements from various DC franchises including Batman Beyond, and the story uses my alternative origin for Terry. Figuring out how to work all the elements together was fun.
