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 can't remember the last time 
I felt envious of another.
.لا أذكر آخر مرّة شعرت فيها بالغيرة من أحد آخر
Wie lange habe ich andere
schon nicht mehr beneidet?
¿Cuánto hacía
que no sentía envidia de otros?
¿Cuánto hacía
que no sentía envidia de otros?
Depuis quand
n’avais-je pas envié quelqu’un ?
Non ricordo quand'è stata l'ultima volta 
che ho provato invidia per qualcuno.
Não me lembro da última
vez que senti inveja.
Даже не помню,
когда я хоть кому-то завидовал.
