i just noticed…
in “every day”, the lyrics go

cosette: i saw you waiting and i knew
marius: waiting for you at your feet
cosette: at your call

aside from marius kissing the tip of cosette’s foot, the theme of “at your feet” also applies to two other pairings, although in a more morbid context. one is eponine and marius —

“Monsieur Marius!” repeated the voice.
This time he could not doubt that he had heard it distinctly; he looked and saw nothing.
“At your feet,” said the voice.

and the other is enjolras and grantaire —

Enjolras, pierced by eight bullets, remained leaning against the wall, as though the balls had nailed him there. Only, his head was bowed.
Grantaire fell at his feet, as though struck by a thunderbolt.

Oh god, I never noticed that Eponine-Grantaire parallel before.
