I really REALLY love the way he watches her walk by in that last gif. I know the script makes him patronizing—especially as there is nothing more cliche than having a woman be Absent Minded and Clumsy (TM)—but just look at his face watching her. He’s not laughing (with or at her), it’s pure and simple adoration.
A point this film could have made clearer is that Raleigh has every reason in the world to not want to drift with someone. And yet he’s immediately willing to drift with Mako—not just willing, he seeks her out and challenges her. He is immediately completely willing to share everything with her, based on nothing. She’s hesitant and careful, but he’s already jumped off the emotional cliff.
