He had never seen her look so happy. Even the day that he told her she was a witch didn't compare to the absolute joy now obvious on her face. It was almost too much for him to bare, to see the people he had loathed from first sight surrounding the woman he had loved for over a decade. Black, being an arrogant git as usual, was pretending to sob onto Lupin's shoulder, while Lupin was smiling amusedly. Pettigrew, who looked rather paler and thinner than when he had left Hogwarts, was standing slightly apart from the group, a look of envy on his face. And Potter, the source of his misery and the one he loathed above all else, on the arm of the woman he loved, a look of pure delight on his arrogant face.
He had never seen her look so beautiful. Her hair, for the first time in living memory, was curled to fall down her back, and she was wearing a long, white dress. He watched as various people he recognized walked up and hugged her. From his enclosed spot in the shadows, Severus Snape managed to hold back tears. She looked so happy. She should not look so happy with someone so… so wrong for her. Severus watched as Black made another joke, saw her laugh, saw her turn her head slightly to look around the crowd. Saw her notice him.
Her green eyes shone with confusion and fear. The others were continuing with conversation, but her eyes were fixed on Severus. She looked around again, then back at Severus. Why are you here? Her eyes seemed to say. She bit her lip in a way that used to drive him crazy. Severus looked back at her, and smiled softly. It's okay, his eyes replied. He nodded, and turned to go, but looked back one more time. Her eyes were still worried, but she nodded back.
"Thank you, Sev," She mouthed. Severus turned and walked back into the shadows. Sev. It seemed a little too late to tell her how much he hated that name.
