"I told Alan what lies behind the word 'Always'." J K Rowling was alluding to a scene in Harry Potter And The Deathly Hallows where Professor Dumbledore asks Snape if he has "grown to care for the boy (Harry Potter), after all" and Snape then shows him his Patronus, which is a doe, a reflection of Lily Evans Potter
Professor Snape may have scared the bejesus out of most of his Hogwarts pupils but between takes, he couldn't have been kinder. As fans raised their wands to honour Alan Rickman, his colleagues from the franchise paid tribute to their late co-star. Here are tributes from those who took Potions lessons from the Half-Blood Prince
"As an actor he was one of the first of the adults on Potter to treat me like a peer rather than a child. Working with him at such a formative age was incredibly important and I will carry the lessons he taught me for the rest of my life and career," Daniel Radcliffe wrote in a tribute to Alan Rickman on social media
In contrast to Alan Rickman's often sneering and supercilious screen persona, fellow actors lamented the death of a warm, witty and generous friend. Actor Ian McKellan said Mr Rickman and Rima Horton were always top of his "dream-list dinner guests". "Alan would by turns be hilarious and indignant and gossipy and generous"
