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...
Oh? There's something on 
your collar again, Yor.
.ماذا؟ ثمّة شيء ما في ياقتك ثانية يا يور
Huch? Du hast schon wieder
was am Kragen.
Vaya. Tienes polvo en el cuello.
Vaya. Tienes polvo en el cuello.
Ah, tu as encore
une poussière sur ton col.
Oh? Hai di nuovo qualcosa sul colletto, Yor.
Ué? Tem uma sujeira na
sua gola de novo, Yor.
Ой… кажется, у тебя снова
что-то на воротнике.
