"I knew a girl, once, who had a really remarkable talent for music, and she didn't know it; never guessed what sweet little things she composed when she was alone, and wouldn't have believed it if anyone had told her."
In the film Mr. Bhaer says that he's not worthy to marry Jo because his hands are empty. Jo is quick to take them and say "Not empty now." Cue the Big Damn Kiss under the Umbrella of Togetherness in the Happy Rain! (It gets better: "Not empty now" is lifted straight from the book.)
Fritz Bhaer, period. Say what you want about Jo/Laurie or the lack of it — that man earns his happy ending in magnificent fashion. After all the waiting, all the hoping — he's been a bachelor for years, after all — he finally finds love and finally gets his girl. And it is beautiful.
A lot of Meg and John's scenes together, whether before or after they're married. Notable is when Meg realizes she does love John after all when she finds herself defending his lack of wealth passionately from Aunt March. Daww.
