Combeferre hadn't worn mourning at Milliways. When he arrived, most of his dearest friends were already here--all except Feuilly and Prouvaire, in fact. He knew they were dead, but to him they were simply--elsewhere, and he had reason to hope they would appear.

But he couldn't fail to notice Enjolras's regular mourning attire. It was a daily tribute to their friends, and a moving expression of Enjolras's grief for them. To see Enjolras reach for light, bright colors--

Combeferre smiles, pulling on his coat, and says nothing. They'd never discussed Enjolras's mourning--they'd never needed to--and there's no need to discuss the end of it now. Enjolras's frame of mind is plain to see. Combeferre, still smiling, suspects his own is equally so.
