This weeks' DC previews are up and while I wouldn't get this one in the mail for awhile a couple of things caught my interest.
No real spoilers, mainly discussing his age.
I'm guessing this take place "5 years ago", I'm not sure if it's being stated that Ollie was 19 the year before or if he's 19 here. Regardless he's mid-20s now. This age really changes how his relationship with Roy is going to be since Roy's 21 in the current books. That means their be closer to brothers than the father/son bit.
Ollies' best friend wasn't who I thought it was but I smiled at the reveal.
