That you think she’s not a character with agency has nothing to do with her being the focal point of her numbers. Fantine has 4 numbers in the show. 2 are absolutely focused on her (IDAD and CtM) and two are choir numbers (At the End of the Day and LovelyLadies/Arrest, although she’s the focal point in “Arrest” again). The two were she’s the focal point are preserved in its entirety in the film and even extended, and the two choir numbers feature Fantine much more prominently than the stage show, even extending her role in them (the show doesn’t have the part of selling the teeth). That’s exactly what Blasty was asking. You misrepresented it to him by saying she’s not the focal point anywhere but in IDAD. And that is simply wrong and has nothing to do with how you perceive her importance as a character due to her agency or lack of it. Blasty already knows Fantine is not known for being the leader of the revolution against oppressors, he was merely asking about her numbers and screentime, if those had been preserved in relation to the show. If you didn’t know this particular because you don’t know the show, perhaps you shouldn’t have used his question to rant again about how unworthy of Oscars you think she is?
And yes, it seems she's to you what Lawrence is for ldw.
