Re:Zero Episode 19

Hakugei Conquest Battle (白鯨攻略戦) is the nineteenth episode of the Re:Zero anime.

Plot
In the new timeline, Subaru changes his approach, deciding to defeat the White Whale before going after the Witch's Cult. Knowing when the White Whale will strike from the previous timeline, Subaru offers Crusch's camp an alliance to battle the White Whale in exchange for shared mining rights of magic stones in Roswaal's domain. She agrees when Subaru uses his cell phone to show the time and location of the attack and offers to draw the whale towards himself. Anastasia's camp also agrees to join the campaign, viewing the whale's presence as detrimental to her interests as well. Crusch is impressed by his skill in gathering support, and Wilhelm lets Subaru know that his wife Theresia, the Sword Saint, was killed by the White Whale created by the Witch of Envy and has devoted his life to defeating it. The next day, Subaru and Rem, riding a ground dragon called Patrasche, with the armies of the Crusch and Anastasia camps, head out to the Flugel tree to wait for the whale to appear. That night, the whale appears at the moment Subaru said it would and the battle begins.

Anime Differences

 * Subaru's negotiations with Crusch happen at night instead of before dinner like the last time he tried to do so. Most of the dialogue during the negotiations is shortened.
 * Russell arrives with Anastasia instead of being there right from the start and in accordance to that most of his dialogue is cut.
 * Subaru and Ferris' conversation is modified to remove any mentions of Fourier Lugnica along with Rem and Wilhelm's appearance and dialogue.
 * Subaru and Ricardo's conversation is modified to remove Anastasia and Crusch's appearance and dialogue. And because of that, most of Ricardo's dialog in the conversation, including any mentions and details of the Kobold race, and Ricardo proclaiming himself as a kobold, was cut and changed to have his conversation with Anastasia off camera. Crusch's part is moved to a separate scene with Subaru.
 * Subaru and Ricardo's conversation at the Lifaus Highway is shortened.
 * Parts of Subaru and Rem's conversation at Flugel's Tree is cut, including the part where he reaffirms his love for Emilia and his promise to have Rem as his second wife if Emilia agrees to polygyny.
 * Wilhelm's cut part during Subaru and Ferris' conversation is moved to a scene at Flugel's Tree.
