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...
You call me outta nowhere and 
tell me to dress like this
اتّصلت بي من العدم وطلبت منّي ارتداء هذه
Der ganze Aufzug nur,
weil du deine Frau verdächtigst?
¿Me llamas de repente para que me ponga
esto e interrogue a tu mujer?
¿Me llamas de repente para que me ponga
esto e interrogue a tu mujer?
Tu m’as fait venir pour me déguiser
et enquêter sur ta femme ?
Mi chiami all'improvviso e poi mi dici di indossare 
questo travestimento per interrogare tua moglie?!
Você me chama do nada e me dá uma
fantasia pra interrogar sua esposa?
Выдернул меня с работы, шмотки всучил,
а теперь на допрос жены ведёшь?!
