Re:Zero kara Hajimeru Isekai Seikatsu 2nd Season Part 2

Synopsis

With a contract now in place, Subaru and Beatrice work with Emilia to use their combined powers to trap the Great Rabbit. Beatrice seals the mabeasts in another dimension using Al Shamac, saving the Sanctuary. Beatrice and Roswaal then visit the grave of Echidna, where he reveals he is in fact the original Roswaal, having figured out how to use soul transcription into each of his ancestors. Meanwhile, Subaru and Emilia reconnect outside, where she mistakenly believes she's pregnant due to their kiss. Most of the group take turns punching Roswaal as punishment for everything he's done, before trying to negotiate what to do next; Subaru knows that they'll still need his assistance in the future. Roswaal reveals that due to their bet, an oath curse has appeared on his chest preventing him from betraying them without dying. They finally agree to believe him, though some reluctantly so; Emilia gets him to apologize. Later, everyone attends a ceremony where Subaru is formally knighted in Emilia's service. Roswaal reveals to Subaru that he ultimately plans to find a way to revive Echidna. Now without the Tome of Wisdom, he expresses his faith in Subaru while also threatening to reduce everyone to ashes should Subaru lose anyone important to him. Alone on a balcony after being knighted, Subaru is met by Emilia where they reaffirm their trust and belief in each other before rejoining the festivities.
