Because he ran away to Bluehaven!  How about you stick around dad!  why were you never there for me?!  WHY WERE YOU NEVER THERE?!<br/><br/>Sorry, my own issues might be spilling over...a bit lol<br/><br/>You know actually if you want.  We could have some history between them.  I could throw in that Huntress made a stop in Bluehaven on the way to Gotham and gave Nightwing a hand with something?  She had a day to kill while she waited for the next train to Gotham and they met up?  Killed a bad guy or two?
