Zach had finally lost the aliens on him, he watched tem crash into another building. Before he flew back to where the team was. He didn't know what Kalinda had in mind for the extra arc reactor. Still he would follow orders since she was Michael's girlfriend and he knew she would want him back more than anything.

He landed on the roof, just behind the main group. He walked up to Kalinda the arc reactor in his hand. He kneeled down next to her and looked at Michael. He still wasn't breathing, he suspected two reasons. Frost had made his chest collapse in on itself or had blown Michael's arc reactor to bits the one that was keeping him alive.
