In order to prove to Yuri that they are actually a married couple, Loid and Yor are supposed to kiss. Loid is willing to get this done immediately for the sake of Operation Strix, but Yor can't do this sober, so she ends up downing a bunch of wine and gets drunk.  Yuri sees his sister this way, also gets drunk, and is unable to make rational decisions anymore...
What a coincidence. Why don't
 we go home together?
يا لها من مصادفة. لماذا لا نعود للمنزل معًا؟
Was für ein Zufall.
Wollen wir zusammen nach Hause gehen?
Qué coincidencia. Volvamos juntos.
Qué coincidencia. Volvamos juntos.
Ça, pour un hasard.
On rentre ensemble ?
Che coincidenza. Torniamo a casa insieme?
Que coincidência.
Vamos voltar juntos?
Вот так совпадение!
Пойдём домой вместе?
