I turned and felt a smile growing on my face.
She considered him for a moment, before a smile grew upon her.
Her smile grew, as if at the thought of something more.
A smile grew on his face as he came closer to it.
But things would change once more, and his smile grew ugly at the thought.
Anna's head came up, and the smile that was already on her face grew when she saw him.
Her smile grew broader as he pulled out his gun.
His smile grew wider as he saw the other's expression.
They stopped for a moment, then their smiles grew wider.
The smile grew until she was almost radiant with it.
