Deathly Hallows chapter 21. After checking in with Buzzfeed to see how they're handling Harry Potter clickbait these days, we finally learn all about the Tale of the Three Brothers: a wizarding world story so common, why, everyone knows of it! We also learn about a bunch of aphorisms and other cultural artifacts that surely anyone would recognize, because they've been part of the wizarding world this whole time and definitely not pulled entirely out of the author's ass just now. Finally, we head over to reddit and quora for a grab bag of third segment goodies.
