Corbinian was on a rooftop when the call from Robin came through over the communicator. He was glad to hear it, reassured that the communicators were being put to good use by the younger masks. Robin was using his precisely the way he had been hoping they would use it - to call for back up if it was needed. He checked the street signs below him. 139th wasn't far. "Corbinian," he said, speaking into the communicator. "I can be there in three minutes." He was already up and moving as he spoke, running off the edge of one building and taking the leap over the alley. That never ceased to get his adrenaline flowing. It had been a slow night thus far. Maybe the 'suspicious activity' would be nothing more than an underground poker game. He didn't precisely hold out hope that it would be something more interesting, but he had to admit, it would be refreshing to turn something up after hours of false starts.
