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...
Just know that you'll rue the day!
!اعلم فحسب أنّك ستندم
Glaub ja nicht,
es wäre schon vorbei!
¡No lo olvides!
¡Que no se te olvide!
Bref, je t’ai à l’œil !
Va beh, vedi di stare in campana!
Só fique sabendo que
você vai se arrepender!
Короче, заруби себе это на носу!
