Wasn't much of a fan after Tom Taylor left the previous volune, but I've picked up issues here and there. I remember seeing Dick Grayson intro'ed in Futures End or whatever, and know how he became Batman, but did he ever have a relationship with Bruce Wayne in this version? Was he ever a Robin there?

I assumed he was a "normal" guy with no training when first intro'ed, but hes depicted as pretty proficient as the current Batman, is this just comic book logic and accept he's a bad ass after a little training and fancy back brace, or did I miss an issue detailing his history as a sidekick and then retirement to start a family?
