Briony stood outside the cell for more than five minutes. During that time, she blocked all her senses temporarily. She just wanted to be quiet. She doesn't want to hear any sounds except for her heart which she is sure is broken. She doesn't want to hear his heartbeat that will only remind her of his existence when all she wanted was to forget him.
But before that, she wanted to do something.
She dried her face with the back of her hand and when she felt that she was calmer than before, she turned her head to look at the cell next to where she was standing.
Sam's cell.
She walked a couple of steps in the direction without even glancing at the one-way mirror. She is determined to forget him and she will start doing it now.
"Open cell B304," Briony said as soon as she stood in front of the steel door.
