Yep, Starling is the traitor, which anyone could predict by her absence from the last few covers, anyone except Black Canary, who kicks herself in the ass for not figuring it out earlier. Turns out Ev and Mr. Freeze are old buddies, but she hasn't turned completely against the Birds, pointing out that the Court of Owls are their ultimate enemy. But, neither Dinah or Batgirl are having any of it, Strix is frozen, and who the hell cares about Condor?
With all the talking Ev points out the Freeze that they're stalling, trying to get Strix free, so Freeze lays down another coat of ice, but has promised not to kill the Birds. In the chaos, the two Court scientists try to escape while Babs starts to fight Ev, and Dinah teams up with Condor against Freeze.
It doesn't take much for Freeze to temporarily best Dinah and Condor, as he just traps them behind an enclosure of ice, then begins to stalk the scientists, while Ev and Babs duke it out.
Freeze finds the two scientists having just been hung up upon by the Grandmaster of the Court, having been informed Mary was there. Freeze begins to torture the scientists, as he wants to know what the regenerative property they used in combination with his tech was... I wonder why.
Dinah ends up using some C4 to blow the ice, and Condor's power to hold back the blast from harming them. But as she gets out, Freeze lets Ev know he has the info he wanted, and to meet at the rendezvous point. Dinah gives chase to Ev, who is still telling her former teammate they can get past it, but Dinah lets out a canary cry that almost brings the hallway down on top of her.
Having been pulled away from the wreckage, and having lost Ev, Dinah turns to freeing Strix from the ice with Bab's help. Dinah has Babs go outside to get Strix in some warmth, but as she heads outside, another Talon, of the Calvin Rose variety is waiting for her.
