Favorite scene is a little harder though. I’ll probably have to go with the montage scene in the last DS9 episode, which had a slow instrumental medley of The Way You Look Tonight and the DS9 incidental music.
I also think the scene in DS9: The Siege of AR-558 where Bashir is playing the recording of I’ll Be Seeing You is really good too. It works even better on a rewatch after you see how important the song becomes to Nog.
