The smile he got in response to that comment was completely involuntary, and small, barely a twitch at the corner of his mouth, but it was there. "I think the couch will be suitable, for the moment." Yes, it was plain as the nose on his face that he was in no mood to even attempt the stairs, but that was beside the point. He was aware enough of his failings without making a list.
He collapsed gracelessly to sit on one end of the couch when they reached it, head tipping back as he shut his eyes once more. His head pounded, and all he wanted, besides a drink, always a drink, was sleep. He dreamed of it. Would, if he was unconscious enough to get to dreaming.
"Where were you?" His question was quiet, carefully spoken with little of the anxiety he felt. Had Enjolras died too? "And Eponine, Gavroche...they're okay?" He was ashamed to realise he hadn't even thought of them until now. It was hard to keep much in the way of thoughts in his head right now.
