Attack On Titan - Season 4 - Episode 3 - The Door of Hope [English Dubbed]

Summary :- Reiner Braun recalls his youth when he trained as a Warrior so that his Eldian mother and Marleyan father could live together. Faced with many struggles and shortcomings, Reiner's dream kept his resolve alive. He recalls his final days in Warrior training when he, Bertholdt Hoover, Annie Leonhart, and Marcel Galliard were sent to Paradis Island to reclaim the Founding Titan.

On their journey, Reiner learned that Marcel set him up to inherit the Armored Titan instead of his brother. Reiner's shock was worsened when, shortly afterward, a Titan consumed Marcel. The Warriors lost hope for their mission after Marcel's death, but Reiner's determination to live and succeed spurred his comrades on. Meanwhile, Falco Grice continues to struggle with his Warrior training, becoming more and more convinced that he has no hope of inheriting the Armored Titan and saving Gabi Braun's life. On his way home from the Warriors' headquarters, Falco meets a wounded soldier who wants to speak with him.
