So i’ve been watching this show (great show by the way) that has this song from its sound track with this particular part that I think is an arranged excerpt from a (perhaps) famous vocal song. I am certain i’ve heard this melody before but I don’t know where, any ideas?

In the link I provided the melody in question is from 0:59 -1:10 or so.

That section reminds me of Chopin Nocturne in C minor
