Zee has, I think been mentioned of course, as John Zatara was a member of Shadowpact before he left it...so yeah I think it's a safe bet we'll see her return at some point.
Read the first part of "Teen Titans". There was no issue number, so this might be the first of the new format. I thought it was pretty good. It was written a bit like Geoff Johns Titans run (no surprise really) and "Young Justice". Connor seems to be the natural leader of the group and has already developed a bond with M'Gann (Miss Martian). The Wonder Twins were in their purple jumpsuits. They're being trained by Jay and it seems like this was an idea of Carter Hall's prior to his death. Looking forward to seeing as how this unfolds.
