and he loved her suddenly because she loved him.

He knew she was there by the joy and fear that overwhelmed his heart.

She would love it. Just as he loved her. He paused for a second, his fingers touching the door handle. He was in love. The realisation came to him quite suddenly.

He knew she was there by the joy and terror that took possession of his heart [...] Everything was lit up by her. She was the smile that brightened everything around.

He was glad that he had expressed to her, however blunderingly, what he felt. He was glad that he had held her hand.

"He came to be very glad that he had known her, and that she had had a hand in breaking him in to life. He has known pretty women and clever ones since then, — but never one like her, as she was in her best days. Her eyes, when they laughed for a moment into one`s own, seemed to promise a wild delight that he has not found in life. "I know where it is," they seemed to say, "I could show you!

How did you know He was God?' Gamache asked.
'When does a bush that burns become a Burning Bush?' Em asked and Gamache nodded. 'My despair disappeared. The grief remained, of course, but I knew then that the world wasn't a dark and desperate place. I was so relieved. In that moment I found hope. This strnager with the sign had given it to me. It sounds ridiculous, I know, but suddenly the gloom was lifted.'
She paused a moment, remembering, a smile on her face.

he silently acknowledged he did love her and that he would not hesitate to give his own life to bring her safely back.

"Could we go into your room?" she asked. "I knew it. I knew it," he said, spinning around and sliding quickly toward his door. "It's finally happend, just like in dreams. An intelligent, beautiful woman is going to declare her undying affection"

She is sighing deeply now with sympathy and delight - the delight of an addict when someone else admits he's hooked, too.

He stared at her, knowing with certainty that he was falling in love. He pulled her close and kissed her beneath a blanket of stars, wondering how on earth he'd been lucky enough to find her.

His despair at life had metamorphosed into hope.

She ran up the rest of the way up and stopped in front of him out of breath[...] 'It's you!' she said, breathless and happy, seizing his arm"

She’d been happier with him than she had ever thought imaginable, but only now she understood it wasn’t because their DNA had dictated it, but because she’d opened herself up to the concept of love.
