Ally walked into Mac's office. He was talking with Flake

"Hey, I need something." Mac looked up from his file.

"What is it." Alison held up a piece of paper. "My resulted were negative." Mac set the file down.

"You're kidding me. That can't be right." Alison nodded.

"I know." Mac looked over at the lab.

"Maybe it's a false negative," Mac suggested.

"Yeah, but I only have enough to run it one more time. I would hate it us it on a machine that isn't working." Mac pinched the bridge on his nose.

"Go see if Greg got anything. If not, then we'll go from there." Alison turned to head down the hall when an explosion went off. She ran in the direction it came from. The closer she got, the more worried as it was the lab that Greg had been working in when she last saw him. Rounding the corner, she saw him lying on the ground. He had been blown through the glass. She ran over to him, doing her best not to touch him.

"Greg! Greg, can you hear me." She repeated his eyes were closed, but he was breathing. She looked around them to see what had caused it, but there weren't any clear signs. She didn't notice the time pass. She was so focused on counting his breath. She felt someone pulling her back. She tried to fight it, but after seeing that it was Flack, she moved back. The Medics treated Greg and rolled him out of the lab. She slowly followed them until they reached the ambulance.

"Are you coming." The paramedic asked as they lifted Greg into the back of it. She took a step forward then stopped shaking her head; her eyes locked on the heart monitor. She looked to her left, where Flack was still standing. He gave a small nod.

"I'm coming." He hopped in, sitting next to Greg. They rode away, and Alison bounced on her feet.

"I'm sorry," Mac said, standing next to her. She closed her eyes, taking a deep breath.

"That doesn't make it any easier."

Alison stood in front of the hospital.

"Do you want to go in," Frank whispered in her ear. She gave a small nod, not trusting her own voice. Frank grabbed her hand after she put her headphones in turning on the music. "Then well go as slow as you need. They eventually made it to the hall outside Greg's room. Flack spotted them walking over to them.

"He has a few full-thickness burns, but the doctor says he will make a full recovery." Alison stuck her hand in her pocket. "He's been asking for you." Frank squeezed her shoulder.

"He's not on any monitors, so there is no noise," Flack added. Alison pulled her arms tight around her and walked into the room. Flack and Frank watched her take her headphones out.

"I never thought I would see her do something like that," Flack said, letting a small smile cross his face.

"Yeah, I just pray he doesn't hurt her." Alison was sitting in the chair next to the bed, one hand holding Greg's the other wrapped tightly around her body.

"How are you doing." She whispered out. He gave a small smile.

"Better now that you're here." Alison looked at the door.

"I'm sorry I wasn't here sooner." Greg looked into her eyes. He could see a small glimmer of fear in them.

"Your timing's perfect."
