“I won’t lose you, Padme. I can’t” He sat forward and twisted to take both of her hands, small and soft and deceptively strong and beyond precious , between his own. “I am still learning, Padme—I have found a key to truths deeper than the Jedi could ever teach me. I will become so powerful that I will keep you safe. Forever. I will.”
“You don’t need more power, Anakin.” She gently extricated one of her hands and used it to draw him close. “I believe you can save me from anything, just as you are.”
She pulled him to her and their lips met, and Anakin gave himself to the kiss, and while it lasted, he believed it, too.

I wish they would have kept that kiss in the movie :(
