Les Miserables deleted scenes:
Eponine and Gavroche

From this featurette about Sam Barks. I mean, I’m assuming this is a scene being rehearsed or filmed- the people talking in the background make me wonder- but Sam definitely seems to be in full-on Eponine mode, so…

I have no idea what lines she’s singing, as this bit in the video has a voiceover, but I’m guessing it would be “We were children together/Look what’s become of me” as Sam’s expressions are close to what they were for that bit in the final film, and because it’s a nice nod to Eponine and Gavroche being brother and sister.
