• When Padmé first meets Anakin since their 10 year absence, she's initially impressed with how much he had grown and how handsome he had turned out. But nothing more. She still saw him as a "that little boy she knew on Tatooine" still calling him Ani from time to time.
• On the refugee transport to Naboo Anakin and Padmé finally get a chance to talk. Padmé states that it must be very difficult being a Jedi and that you could not go anywhere or do anything you like, Anakin, very abruptly shifts the conversation into love. Padmé is a bit stunned but amused that he would mention love. For the Jedi were forbidden from it. Anakin's nerves crack a little bit when she gazes at him. Anakin reveals a side of himself that is very intelligent and romantic and she picks up on it. This is when Padmé first begins to "notice" Anakin. She makes a comment of how much he has changed but really telling him how handsome she thought he was.
• Standing by the lake with Anakin, Padmé is wearing her first informal dress that's very flowy, eye-catching with an open back, showing more skin than we have ever seen before. This dress speaks volumes to how she is feeling. She is comfortable around Anakin to reveal her skin around him and that she was physically attracted to him. As she reminisces on her happy childhood Anakin tried to forget his. It's then that Anakin subtlety touches her. First he strokes her hand, she allows it, then he moves his hand and gently strokes her back, this is a different kind of touch. It's very bold and very sexy. Anakin is sending a very clear message. He leans into her giving her plenty of time pull away, he kisses her and she kisses him back. Its safe to say she is very physically attracted to him at this point.
• Her attraction only grows over time but its not until he loses his mother she starts falling in love with him.
