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...
Hey, now. You're going to 
bother the people downstairs.
.على مهلك. ستزعجين الجيران في الأسفل
Hey, trampel nicht so,
unter uns wohnen Leute.
No hagas eso, molestarás
a los vecinos de abajo.
Para, que eso molesta
a los vecinos de abajo.
Ne saute pas,
pense aux voisins du dessous.
Non agitarti così.
Disturberai gli abitanti del piano di sotto.
Ei, vai incomodar os
vizinhos de baixo...
А ну, не прыгай!
Под нами, вообще-то, люди живут.
