Alan Rickman once said that J.K. Rowling gave him a "tiny, little, left of field piece of information" that allowed him to understand the character of Severus Snape better and thus more accurately portray him. I told Alan what lies behind the word 'always'. https://t.co/NHTJ5J6kxb As Harry Potter fans know, that is the word Snape uses to describe his perpetual love of Lily Potter, at the end of the series.
