Reiner is shocked by Eren's presence in Marley, and begins breaking down after Eren indirectly threatens the civilians watching the festival above. Falco is instructed to stay in the room. Lord Tybur finishes his preparations, as crowds take their seats. The presentation begins, and an apparent Marleyan soldier summons the Warriors on behalf of Magath.

Reiner questions Eren on why he came to Marley. Then they begin to listen to Willy's speech, where he recounts the understood history of the world. Eren and Reiner continue talking, and Pieck and Porco are led into a room, where a trap door is pulled underneath them. Falco realizes Eren is from Paradis, whilst Willy declares that the known history is a lie. He explains it was King Fritz who saved the world, and never actually posed a threat.
