It’s interesting to look back on the affect that Emma had on Graham, now that we’ve seen her touch Regina and make the hat work, and also touch the wardrobe which resulted in magical ashes. Kissing Graham was the only time she completely let her guard down with someone, (prior to her kissing Henry), and look what happened…she started to change how magic worked on him. That doesn’t mean it was a true love kiss breaking his curse, it just means that she let down her guard, opened herself up, and her power to change magic started to rev up.
