Marcus did little to nothing as he stood at the gate, waiting for something to happen. His head immediately turned to face Jacob as he saw his signal. It took almost no time at all to open the gates. He also heard the howl that could have only come from fen, and he wasn't quite sure what to make of it. He wanted to continue thinking about the howl, but he didn't have the time to do so. His business was with the gate, and as soon as the solar car passed into the city, he closed the gates quickly and looked at the car. The bionic man simply stood there and identified two of the four people as Claudette and Tobias. He didn't know the harpy enough to use her nickname, and even if he did he wouldn't use it. 

For the first time in several hours, he took his complete attention off of the gate to get to the solar car and inspect who the other two people were. They were children, he knew that just by looking, but they weren't any that he had ever seen. He looked at the last harpy and the Alpha, saying nothing to them as he simply nodded to them with a slightly softened look on his face. The moment didn't last long as he walked back to the gate and moved all of his attention back to the metal wall. People were still out there, and he didn't know the current status about the dead that were supposed to be attacking soon.
