Christmas Crash (DC/Young Justice/Batman Beyond Fanfic

Out of stubbornness Nightwing quits the family business, only for family to drag him back in. In particular, one stubborn Robin ticking off a serial kidnapper as himself rather than as Robin. Oh, and Christmas stinks, but once a hero, always a hero, and Damien remains Damien, an evil little twerp who learned "good" ways to be evil and tormenting.

Disclaimer - I don't own DC. I'm utilizing elements from the Young Justice, Batman Beyond and other series, as Damien never shows in either. AU origin for Terry, but more specifically, Batman's not his father genetically but related in a different way. At this point, Terry's parents are already divorced. Also, I like the idea of Warren always being aware of the fact Terry's not his biologically, but not caring. Some of the other plot twists though are left a secret.
