Aria/Tear Jerker


 * The two-parter in Natural where Akari has to say goodbye to her gondola. It hadn't been treated as a character, but as you see the history behind it and come to realize how important it really was, the dream sequence where  In the next episode, when , while the lyrics "Safe on a rainy day/ I'll miss you..." play, it's just so beautiful and sad at the same time.
 * Alice's promotion in Origination. First we see her throughout the whole episode showing how she'd grown since she was that shy, quiet girl way back in Animation. Then, she shows how great an Undine she is as she takes Athena for a tour. In the lock, Athena tells her not to worry about her singing, and just to sing. Then, on Hope Hill, where all her friends have gathered, she sings a beautiful song. Seeing Athena take off Alice's first glove gives a sense of fulfillment to the episode.  The promotion is so incredibly well-done.
 * Athena reached to remove the other glove as the discussion about singing and the actual song request were the biggest elements of foreshadowing that Alice was secretly being given both promotion tests at the same time. It's made even more powerful after having spent the entire series up to this point wondering, "Why hasn't Alice been promoted to a Single yet?"
 * The last episode. Dear god, the whole episode. Every part of the whole episode. The mailman... the ceremony... the flashback scenes and the hug... and Ai too. All of it. Just... wonderful. All the wonderful things on Aqua that you've seen in the past 52 episodes just flow through you like Neo-Venezia's canals, spreading love. And you just can't help but cry...
 * Episode 12 of the first season made. Just...the scene where the water is released.
 * The episode where Akari delivers the old letter to the grave of the recipient, knowing the message was recorded by his wife who had yet to hear of his death.
