Hey, I really liked this, especially the ending, where the sepia illustrations took it back to the world of Katie's fics, and sort of made it back about the relationship we can't see (on screen, in canon pages), and the way she overlays the music of love and longing onto the familiar bodies to make them aching and hurting in a way we don't get to see, but we know exists.
I really like what you do with the exchange of glances, too.
