I agree with SaraBeth. It has been apparent for some time that Aiden has deep feelings for Hope, and I think their friendship has taken a wonderfully slow path to now. Both have been aware of the feelings that have developed for the other person.
Today, Aiden knew Hope had questions about his past, and she said yes, but she respected his privacy. He said he knew that, because she could have checked his background long ago. And then she shuts off her computer, he says "you're not going to read it?" . And she says no, I want you to tell me yourself what happened. And boy, when Aiden went into the story, haltingly, but truthfully, telling it all, and then, at the end, tears in his eyes. Hope said words of comfort, and they evidently were perfect for the moment, as he he just blurted out "I love you", and kissed her. The way he held her face, so tenderly. She was touched. Oh, well, done, very well done, indeed. Loved it.
