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...
I totally forgot to bug their
 living room and bedrooms!
نسيت تمامًا وضع أجهزة تنصّت
!في غرف معيشتهم ونومهم
¡Olvidé colocar aparatos de escucha
en la sala y en el dormitorio!
¡Olvidé colocar aparatos de escucha
en la sala y en el dormitorio!
J’ai oublié de poser des mouchards
dans leur appart.
Ho scordato di piazzare delle cimici 
in salotto e in camera da letto!
Esqueci por completo de
grampear a sala e os quartos!
Совсем забыл поставить им жучки
в спальне и гостиной…
