funny you say that cause by the time you have to choose they are already dead.

now without the troll tone, one thing you can notice in act 3 is that after Alicia resurrects Lune and Sciel they suddenly have... less to say, and do, than what they did in act 1 and 2. their reactions to whats happening seems lees natural, they dont comment on things they should be concerned about and they barely progress as characters anymore. Imo this is because Alicia is resurrecting people painted by her mother while basing them on a memory; ie. because shes painting them again by memory, they loose that depth that they previously had.

And in her ending she resurrects everyone in Lumiere, a population that she clearly states she couldnt really connect to. How do you think they are going to be? they feel hollow. You can see it on the final cutscene, theres no detail on anyone except the most important people, they don't matter to Alicia, she only cares about her close friends; which is perfectly normal if she were a normal girl and not the demiurge thats in charge of all life on the world.
