"Some day, my prince will come, Some day, we'll meet again." And by golly, he did.
The part where Snow White helps the little blue bird.
The fact that, of all the dwarfs, it's GRUMPY that leads the charge to avenge Snow White against the Queen.
Grumpy turns out to be very affectionate with Snow, and it's beautiful.
The huntsman deserves a heartwarming moment. He's put in a position where he must either kill Snow White or face execution. He makes sure that her back is turned because he doesn't want to look her in the eyes. To top it off when she catches him trying the second he looks at her scared face he drops the knife and begins sobbing begging for her forgiveness, warning her that the Queen is out to get her and telling her to run for it.
