Attack On Titan - Season 4 - Episode 10 - A Sound Argument [English Subbed]

Summary :- Two years ago, with assistance from Zeke Jaeger and the Anti-Marleyan Volunteers, Paradis Island was put in contact with an old ally in the nation of Hizuru. Their envoy, Kiyomi Azumabito laid out the three part plan to keep the island safe until a time it will not need to rely on threatening the world with the rumbling. However, Hizuru's assistance came from a place of greed and a year later they would not help Paradis negotiate trade with other nations in hopes of keeping any profit from Paradis's resources for themselves. Hange Zoë concluded that the Scout Regiment would have to venture out into the world themselves and meet people firsthand.

In the present, Eren Jaeger's behavior perplexes those around him, and his friends try to come to grips with the person which he currently is with the person they remember. Historia Reiss is now pregnant, which is delaying the transfer of Zeke's Beast Titan to her out of concern that the process could harm her or even kill her unborn child.
