It wasn't that he didn't like music. He did. Always had. But it had been a long time since he thought of just putting a CD on, letting the words and melodies fill the house.

JJ changed all that. When things fell apart with LaMontagne, he had offered his spare room to her and Henry. It wasn't an entirely selfless act - he and Jack needed the company, and for some reason, both he and his son felt safe with them.

It had been a long time since he'd really talked to anyone, too. But he and JJ would stay up late into the night, talking, laughing, sharing...like tonight. She had picked up the habit of falling asleep on his shoulder, and he couldn't help but wrap an arm around her and just sit there for awhile.

Closing his eyes, he let the music from one of her CDs wash over him. The beat was low and deep, and he felt it right through to his bones. Each strike of the drums sent a shiver through him, and he felt his breath catching. He looked at JJ again and wondered if she could feel it, too.

His fingers ran through her hair of their own accord, and she stirred, lifting her head to look at him with sleepy eyes.

And he couldn't help it.

He kissed her.

The drums filled him completely then, shaking him to the core, moving him, sweeping him along with the beat. And when her hand slid around the back of his neck and she kissed him back, he knew it.

She felt it, too.
