“The only time my editor ever saw me cry was over the fate of Teddy. ”

J.K. Rowling shared a sweet tribute to everyone’s favorite Defense Against the Dark Arts professor on her Twitter page, today. May 2nd, 2016 marks 18 years after the Battle of Hogwarts took place in Rowling’s finale novel to her Harry Potter series. 18 years after the death of Remus John Lupin.

Once again, it’s the anniversary of the Battle of Hogwarts so, as promised, I shall apologise for a death. This year: Remus Lupin.

Arthur lived, so Lupin had to die. I’m sorry. I didn’t enjoy doing it. The only time my editor ever saw me cry was over the fate of Teddy. 😢

In past years, Rowling has apologized for killing off other characters in the final battle, and for many these tweets of remorse (not regret, mind you) bring a sort of closure to the sadness of our childhoods.

She adds in another tweet that she hadn’t planned on having Lupin killed until her time writing the fifth book, The Order of the Phoenix, where she no doubt decided that Lupin and Tonks would end up together and with child, a boy  named Teddy who would be orphaned by the end of the series. Not unlike our protagonist, Harry.

Beautifully, Rowling shared a response from a Potter fan who has cherished Remus Lupin as a favorite character.

The best tribute he could have. https://t.co/SwY6vlXVPu

We remember the Battle of Hogwarts, and we celebrate the end to a fantastic tale. An ending we had no idea would flourish into a new beginning with The Cursed Child.
