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.
Actually, you just stay here and 
don't do anything, I suppose.
،في الواقع، ابقي هنا ولا تفعلي شيئاً
على ما أفترض
Bleib einfach hier und sei ruhig.
Mejor espera aquí.
Será que mejor que tú esperes aquí.
Décidément,
tu ferais mieux de rester cachée ici.
Lascia perdere, tu resta pure qui
senza far nulla, oserei dire.
Sabia. Você precisa ficar
aqui quietinha, imagino.
Наверное, тебе стоит тихонько 
посидеть в лаборатории.
