He watched her fall, right out of his life. That angel who had made everything better, made the world (his world, at least) a little brighter. He could feel his heart go with her.

He screamed her name, begging her to come back, knowing that she couldn't. Afterwards, he couldn't figure out where he got the strength to pull the lab door open, couldn't figure out where the sudden burst of courage that moved him to grab the parachute had come from (he didn't even pass his field assesment, for Pete's sake). The only explaination he had come up with was that it was her. She always had brought out the best in him, made him stronger than he ever would've been on his own.

He was beyond relieved when they fished her and Ward out of the water, even if he was a little miffed that Ward had been the one to save her, not him.

Later on, after everyone bunked down for the night, Simmons came to him and told him that he was the hero. And then she kissed him.

Mind you, it was only on the cheek, but it was a start. As he watched her walk out of his room, Leo Fitz could only be grateful that she had been saved.

Leo Fitz was a man of science, he did not regularly rely on faith, but he was grateful to whatever force that had let her return him. They had given him a second chance.

And he sure as hell wasn't going to waste it.
