We know they are all miserable but who's the MOST miserable? Ranked in order from sad to most sad.
Thénardier - sad but still living life
He's sad because he's not as rich as he wants to be, but hey, he's got the jolliest song in the musical.
Madame Thénardier - also sad, but dealing with it
More sad than her husband because they have equal problems (now who will get their damn water after Cosette leaves??), and additionally she can't get her hair under control.
Gavroche - sad-ish
The little kid was really happy and bound to be a pretty cool teenager...that is until he died.
The barricade boys - sad but drunk
The beer relieves them of their sadness, but...they all still die.
