It was a damned shame. Nick couldn't help but think that as he watched the Crimson Dynamo, the beleaguered Tony Stark inside, tearing down the door. They worked so well together, Stark didn't even need directives. Stark knew what needed to be done, and he did it. Like Nick, he was a man who understood what it was like to have the world on his shoulders, but when the going got tough Nick and Tony coped differently. It was Tony's coping mechanism that was a damned shame.
For all that Nick wanted to condemn him for the alcoholism and the Extremis (neither of which had lead to the terrible consequences he'd been expecting) and for giving up the suit, Nick couldn't deny the fact that Tony was here. When there was a problem, he'd called Nick, and he'd come through and the motherfucker had done what needed to be done. Nick probably owed him an apology, but that could wait until after they saved the world.
Nick wasn't just being arrogant here, they probably were saving a lot of the world here, because Nick had no idea how many nukes there were and where they were programmed to go. Of course, his contacts had gone conveniently silent. He waited for the door to finish "opening" and then he ducked into the control room. Screens and machines lined the walls and there were five guards waiting to be taken down. Nick made a vague gesture towards the panels for Tony to get to that while he tackled the problem of the guards.
