A/N: So I definitely took this differently than intended, but I read the prompt and this is immediately what came to mind
prompt 2: the sun on your face
The shop door tinkles and Mrs. Lovett pushes her way in, watching Sweeney Todd stare out the window as he always does, silver razor in his hand. "Brought ya some supper, love," she says, shifting the tray so that she holds it on her hip. He continues to stare, his back to her, and she huffs. "Mr T!" she calls again, but he merely lifts the razor in front of him. The sun is setting now, tendrils of light snaking through the thick window panes. As he rotates the razor in front of her Mrs. Lovett clucks and steps toward him, watching his face. The razor catches roving beams of light and glimmers, and Mr. Todd's face changes immediately. His lips part in silent admiration and his eyes hold a look Nellie recognizes from when he had looked at Lucy. She can only hope that someday he will gaze at her like that, that perhaps she could be the recipient of his admiration.
