Sometimes she wonders. Does he ever think of her? Does he even remember her? Can he remember? She feels guilty about it, but deep dawn she hopes not. Because for the first time in her life, she is living for someone else. And as selfish as it sounds, she doesn't want to share him. Not even with his mother.

Kate often watches Aaron as he sleeps. In the moonlight, he looks like an angel. Her guardian angel. Because in reality, he has saved her. Saved her from herself.

She remembers. How could she not? Every time she looks at him, she sees her. Claire. The woman who gave her the most precious gift possible. The gift of life. Claire gave Kate her child.

Kate sometimes wonders why. Why her? Of all the candidates, all the possibilities, all the choices Claire had for a guardian for her son. Why a fugitive?

She thinks of that day every time she sees him smile. Her smile. The last expression the blond Australian had worn. The one still on her lips as she died. And Kate's eyes fill with tears as she remembers the letter, that fateful letter, the one written in that beautiful bold script that did not betray the frailty the sickness had wrought on it's author. The letter that willed Aaron to her. It would forever remain her favorite piece of literature.

And every once in a while she wonders. Wonders what life would be like without him. For the responsibility of raising a child means the she will never again be truly free. And yet she knows, even as she wonders, that she wouldn't trade him for anything. Not for Jack, and not for freedom.

Sometimes Kate wonders. But she quickly stops herself because in the end, it's irrelevant . He is hers, just as she is his. They have each other now. And that's all that truly matters.
