If I were Eponine
I would not sing “On My Own”
I would move on and go for Enjolras, Sure Marius in the motion picture looks well bred and classy but Enjolras is rugged, macho, charismatic, principled and better looking.
However I think Enjolras looked at Marius the same way a besotted man would look at a woman [the same way Spock (Quinto) looked at Kirk : I knew Quinto was gay when I saw that scene].
Eponine got herself killed in order to save Marius!…….. stupid girl.
