"Why don't we stay? We can't let... what happened... ruin our time here, after all." She bit her lip, hoping he wouldn't mind staying. Lily noticed that he did not let go of her, but she very much liked that, and made no move to pull away either.
She would have been totally delighted if Severus kissed her or asked to dance, but she knew he would when he was ready. Lily did not want to push him or make him uncomfortable. Besides, just this closeness with him was one of the best feelings in the world. If this was all he wanted for now, she could live with that.
