Wow, these are some good assessments guys! I think Hannah is absolutely entirely wrapped around Shane's little finger. She is obsessed with him, yet he just wants her because her body is hot and he gets to have big boobs in his face whenever he wants and it helps him boost his ego and feel like a "normal guy in a wheelchair" since he hates being thought of as disabled. She serves his agenda. He's snarky to her, he belittles her and focuses constantly on her body, and parades her around for show to make other men jealous. He's childish and selfish, and she's obsessive and enamoured.
