When Enjolras tells the boys they’re the only barricade left, and Gavroche starts singing Do You Hear The People Sing? Enjolras looks so sad because he knows his friends will die and he knows they know, but still they keep holding on. And Combeferre, he looks at Enjolras and smiles at him, full of belief in him and as if he wants to say: see? We are all in this together. We’re going to do this, you are not alone.
