Sherlock grows up a bit, becomes more of a man, stops being the genius child…he was completely blind, he was completely blindsided by who that present was for, he realizes she cares for him. He realizes she’s really hurting. And he realizes, possibly for the first time in his life, that he doesn’t like what he just did. He thinks ‘I’ve got to fix that.’ He’s been cruel before, but it’s always been sort of accidental, or it’s been minor. And he thinks ‘I’ve got to fix that. That’s not good enough. I can do better than that. And I do care that I’ve just hurt her.’ -Steven Moffat (x)
"I do not think [Eponine] is even consciously aware of what she is going through. She says she loves [Marius], and it is heartbreak because every word he says is a dagger in her. She is going through this with eyes wide open, with an open heart and a desperate longing to feel love. I think it is much deeper because her life is darker. If you go through a break up you feel sad and heartbroken, but you can go and speak to your family and friends. You can deal with it in many ways. She cannot. She does not have family at this stage. At this stage in the film she has turned her back on her family and does not have any friends. He is kind of the only thing in her life that is of any worth, and he is her escapism. So to see that fading, for her, is almost like she sees her life fizzling way, and that puts more importance on this relationship for her."
