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 if she was just acting and this 
was all a lie to get closer to me?
ماذا إن كان هذا مجرّد تمثيل
وكانت تكذب للتّقرّب منّي؟
Was, wenn das alles eine Lüge war,
um an mich ranzukommen?
Puede que todo fuera una actuación
para acercarse a mí.
Puede que todo fuera una actuación
para acercarse a mí.
Et si elle avait joué la comédie
pour t’approcher ?
E se fosse tutta una recita, se mi avesse mentito 
sin da principio solo per avvicinarsi a me?
E se fosse só encenação
para se aproximar de mim?
Допустим, что всё это ложь, игра,
чтобы подобраться ко мне.
