The Last of Us Part 2’s new trailer has the internet buzzing for all sorts of reasons — its excessive violence; its confounding plot; its gorgeous visuals. And just as Naughty Dog expected, fans are hard at work putting together whatever they can based off what we’ve seen from the game today at Paris Games Week. One big realization? Our last preview of the game may not have been what we thought it was at all.

On Outbreak Day, which Last of Us fans and the team at Naughty Dog celebrate on Sept. 26, artist Kevin Tong released a poster for The Last of Us Part 2. All it showed was a bloodstained arm gripping a hammer tightly above a burning car. Vague as it was, the image was enough to convince fans that Joel, hero of the original The Last of Us whose role in the new game remains in question, was back; that had to be his arm, they argued.
