Enjolras is the chief, the leader, of course everybody wants him, his motivation, his instructions, his fervour; they all look at him, follow him, continue to kindle the flame he lights. And grantaire, grantaire knows he is not worthy, he doesn't belong there, the cynic amongst believers, yet they are his friends so with them he will stay. But enjolras isn't his friend, is he, grantaire doesn't deserve to stand and fall by his side. Grantaire stays with his friends, and of course he will die when and where they die, there is no other choice for him. He doesn't belong next to enjolras, he's usurping the place of the right hand and the center, but the moment has come, so he walks up to enjolras
Ok, I know we all love Enjoltaire, and I just noticed that whenever a confession is made, there is a pattern. Usually, when it’s Enjolras, he will use his words and make a sort of speech, something he is very used to. For contrast, Grantaire, if he confesses, usually uses actions, i.e. pulling Enj into a kiss, and he normally doesn’t think things through as much.
See if I were a smarter person I'd draw comparisons to C! Sam and Javert, or I'd talk about how L'manburg was more of The Barricade than it was the American Revolution, or talk about C! Quackity and Eponine - Patton
