The tributes to Alan Rickman [1] seem to get sweeter and more tear-inducing every day. Since learning of the actor's passing [2], fans all over have gathered to pay their respects through social media [3], and for those lucky enough to be in London, people left mementos on Platform 9 3/4 [4].

The most touching tribute of all, however, may have been a single lily left outside Professor Snape's door at The Wizarding World of Harry Potter in Orlando, FL — a reference to Severus Snape's undying love for Lily Potter in the books and movies. 

The powerful photo, posted by Instagram user sxpnce, is enough to break anyone's heart.
