Hakkai touches an orb that's already glowing, giving him flashes of someone's memories. It's a young male merchant who used to live in the city, selling the potions they saw earlier. It's about him using one of the potions: duplicating items. He duplicates a vase to show off how the potion works.

The memory ends there and the orb starts to spread black mist towards Hakkai. A mist that will make any part of the body it touches blackened and painful - a curse that will slowly spread through the body if not taken out. He has enough time to pull his hand out, however - or have Eren to do it for him.
