When Roswaal happily tells the story of how his romance with Echidna began 400 years ago, Beatrice rebukes him for casually calling it a "romance." Ryuzu interrupts to comment that Echidna saved her, as well. The one thing these three very different people share is their gratitude toward Echidna. But their days spent in both amicable and argumentative conversation about Echidna are brought to an end by one man's arrival.
Yeah. They're the memories of Ryuzu Meyer 
that Shima-san saw in the graveyard.
أجل. إنّها ذكريات ريوزو ميير التي رأتها
شيما-سان في المقبرة
Ja. Das sind Lewes Meyers Erinnerungen,
die Frau Shima im Grab gesehen hat.
Sí.
Sí.
Oui.
Già, erano i ricordi di Ryuzu Meyer.
La signora Shima li ha visti nel cimitero.
Sim. São as memórias da Ryuzu Meyer
que a Shima-san viu no cemitério.
