Yeah that was my line of thinking for sure they would of had other prisoners because what were they doing before the Titans showed up then doing the Electric Slide to kill time? Rachel saved them all as what we got a few more Episodes of the Season awwhhh..Did Dick just have Kory murder dozens of people? Did they at least check to make sure there were no other prisoners at the asylum before they blew it up?
Oh well.. Nightwing is coming :mark
You are no longer Robin...you shall be called Darth Nightwing!
