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...

!سأغيّر كلّ شيء كما كان
Ähm … Wir schlafen natürlich

Cada uno en su cama, claro. Retiro esto.

Rimetto tutto a posto!
Ah, em camas separadas, é claro!
Vou mudar para como estava antes!
Ой! Подожди! Раздельно! Минутку!
