Why this episode matters

The Season 3 finale is also the series finale, since the show adapts Jenny Han’s three-book trilogy and Season 3 covers the last book, so there’s no planned Season 4. Fans have been following weekly releases from July 16 up to this last 11th episode on September 17, turning it into a big end-of-summer TV moment.

If you want to avoid spoilers, you’ll probably want to watch as close to your local release time as possible, since the finale is being heavily discussed online on release day.
