The Scouts had finally made it to the ocean, and as such, the people of Paradis were able to expand their land to the shores. During one of their patrols of the shoreline, some of the soldiers had found a person washed up on shore. They had almost shot the person, assuming them to be a Marleyean.

The person instead had been brought back for questioning after claiming to not be Marleyean and having valuable information.

Hearing this, Eren goes to question them.
