I LOVE THIS SCENE SO MUCH! It’s so beautifully composed especially with the sunset too! It’s just gives off the perfect feel of a conclusion to the episode’s story!
Usagi’s singing getting Ami to join in too, something Ami WOULD NOT have done before Act 2, when she used to hides the fact that she enjoy Minako’s songs.
Rei is just so adorable here! I think this is where it shows me that Rei is now FULLY ready to accept what friendship with Ami and Usagi would entail. Yes, we have the verbal cues later too, but this is so much more meaningful. Again, Rei’s an “action speak louder than words” person, she has established the fact she hates singing already, and obviously she knows friendship with Usagi means a lot of singing in her life, but she’s found another enjoyment to that despite not enjoying the prospect of singing herself. She is now willing to find ways to adapt to the friendship and enjoy herself even if Usagi’s doing something she doesn’t necessarily personally enjoy.
Ami is so happy to see Rei waving the stick to the rhythm of their singing, showing interest and whatnot! Ami’s experience in easing into friendship has so much parallel to Rei’s and I think that itself makes Ami not only much more attuned to Rei’s thoughts and feelings, but also appreciative of the challenges and barrier Rei would need to cross and IS already crossing in order to open up to them.
This is still something that Usagi still needs growing up in. She sees Rei finding ways to enjoy herself and immediately thinks maybe Rei changed her mind, and so offers another Karaoke party, not realizing the boundaries Rei still has in place. Sadly that only sets her up to failure, where Rei simply says no to the Karaoke idea, though she’s nicer about it now.
