Did you mean win over Emmett? lol
It was somewhere around the middle, maybe a little before I think. It was during the second car wash scene I believe. You should watch though. Emmett and Daphne are arguing and Emmett says some very true things to her before they kiss.
It was clear to me, Emmett just thought of her as a friend at the end and they "appeared" to be frienRAB but Daphne has other motives but they hugged goodbye as Emmett went off with Wilke and Toby to the show.
That is another thing I love about what Bay has done for Emmett. She has opened up his mind more as proof by the fact that in the end, he went to play in the show.
