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...
Apparently, I'm such a failure as wife that 
I can't even keep up proper appearances.
يبدو أنّني فاشلة كزوجة لدرجة أنّني
.لا أستطيع حتّى الحفاظ على مظهر لائق
Ich bin wirklich eine furchtbare Ehefrau,
die nicht mal auf ihr Aussehen achtet.
Soy una esposa inútil que ni siquiera
sabe cuidar de su aspecto.
Soy una esposa inútil que ni siquiera

Je suis une piètre épouse
qui ne soigne même pas son apparence.
A quanto pare sono una moglie così pessima 
che non riesco nemmeno a badare al mio aspetto.
Parece que sou uma esposa tão ruim
que nem consigo manter as aparências.
Плохая я жена…
