It's a nice, short piece of music for sure, I like how it briefly works in the "Scandalous" theme for Vicky, but ultimately it doesn't add much to the scene, which is probably why it just abruptly ends.
Just what Tom said. It's a nice short piece which is much better on it's own. It doesn't really work in the movie and Im glad they decided to not use it at the end. The scene is better without it.
