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.
You're smiling, but that's not 
an agreeable look on your face.
تبتسمين، لكن لا تبدو نظراتكِ راضية
Du lächelst irgendwie mit
einem unverständlichen Gesicht.
No me gusta cómo estás sonriendo.
No me gusta cómo estás sonriendo.
Ton sourire dégage quelque chose
d’indiciblement lugubre.
Stai sorridendo,
con un'espressione che non sembra affatto felice.
Você está com um sorriso desagradável.
Знаешь, меня что-то 
настораживает в твоей улыбке.
