JK Rowling Reveals What It is She Told Alan Rickman About Playing Severus Snape

It's long been known that Alan Rickman knew Snape's secret before the rest of us, because JK Rowling told him and only him something about Snape's fate.

In fact, there were times this knowledge affected what happened on set: "a director would tell Alan what to do in a scene and he would say something like, 'No I can't do that – I know what is going to happen and you don't.'" But what exactly did Rowling tell him?

The meaning of the word "always."

BRB, feelings.
