She's gone. She's really gone. House slowly slunk down beside his piano, an empty bottle of whiskey in his hand.

How can I just let you walk away, just let you leave without a trace

When I stand here taking every breath with you, ooh

You're the only one who really knew me at all.

He hadn't meant what he said to her. "Lisa…" he murmured quietly. Oh, how he missed her so much. He was such an idiot, such a fool. He hadn't stopped her when she took one last look at him, and left.

How can you just walk away from me,

when all I can do is watch you leave

Because we've shared the laughter and the pain and even shared the tears

You're the only one who really knew me at all.

As he slowly staggered up, he sat at his piano, refusing to let the tears, all the hurt fall out. He gently laid his hands over the piano keys, his head bowed.

So take a look at me now, oh there's just an empty space

And there's nothing left here to remind me,

just the memory of your face

Ooh take a look at me now, well there's just an empty space

And you coming back to me is against the odds and that's what I've got to face.

The only other time this had happened was with Stacy. The only two women he had ever loved. And he knew for sure, Lisa Cuddy wasn't going to come back to him, not after what he had done to her.

I wish I could just make you turn around,

turn around and see me cry

There's so much I need to say to you,

so many reasons why

You're the only one who really knew me at all.

He was so sorry, so terribly sorry. He just couldn't change. No matter how many times he told himself he could, for the one he loved- he hadn't.

But to wait for you, is all I can do and that's what I've got to face

Take a good look at me now, cos I'll still be standing here

And you coming back to me is against all odds

It's the chance I've gotta take.

If only he had one more chance. He closed his eyes, breathing heavily. Silence…then there was a knock at the door. He didn't want to see anybody right now, not in this state he was in. The knocking grew faster, then silence. Then out of the heavens, there seemed to be a gently voice calling out. "Greg…"

House nearly stumbled over himself as he staggered to the doorway. He opened the door and…there she was. The love of his life.

You're the only one who really knew me at all
