On May 2, the 17th anniversary of the Battle of Hogwarts, Rowling tweeted an apology for killing of one of Harry Potter's most beloved characters.
Today I would just like to say: I'm really sorry about Fred. *Bows head in acceptance of your reasonable ire*
It incited a lot of feelings from Potterheads.

One of the fans even asked about Tonks and Lupin.
@jk_rowling What about Tonks, Lupin ?
To which Rowling answered:
.@Brieuc26Rankin I thought I might apologise for one death per anniversary. Fred was the worst for me, so I started with him.
We're right there with you, Rowling.
