"I missed him," the words were light, despite being marred by his own tears. And Regulus knew that move. That tone; that crooked grin and the tilting of his head and the slight appearance of the dimple in his cheek. He knew the strain and the game and his inability to grieve. James Potter did not know how to grieve. James Potter did not know how to lose. James Potter knew how to let others grieve; how to talk others through their emotions and hold them while they processed and whisper soothing words that their feelings were valid.
