1."Can you believe the Captain remembered my birthday? He really does care!" Absolutely the funniest part ever

2."MELON LORD!" Toph is awesome

3. The scene where Iroh and Zuko were reunited was so beautiful it made me cry.

4. The battle scenes were just so completely amazing that I forgot to breathe a couple of times. The Zuko/Azula fight was beautiful in every way possible. And Aang vs. Ozai was too epic for words.

5. The Kataang kiss at the end. I've been a Zutara shipper for almost the whole series and that one kiss converted me to Kataang. I still like Zutara but I never thought it was possible for me to actually like Kataang being canon.

6.The scene when Zuko and Aang were talking before Zuko became Fire Lord.
