- Angel's line asking Otonashi "Why are you still sitting" after he reaches out to her is rather heartwarming given how lonely she seems. This effect is threatened given that until she had asked him that, most viewers would believe she was extremely angry given her general lack of emotion, and that she had started to walk out of the room. Hell, their entire light-romance-ish subplot is extremely heartwarming in light of the tearjerkers that sandwich it.

- Also in episode 12, the end credits show everybody, even the ones who ascended. It's a nice touch. And by the end, a new part of "Brave Song" is playing, changing the mood of the song from somber and melancholic to something closer to triumphant, as a way to signify that Yuri's fight is finally over, and she accomplished something extraordinary both for her friends and with the help of her friends.
