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...
Then I guess I'll just have 
to wait patiently for you.
.أعتقد إذًا أنّني سأنتظرك بكلّ صبر
Dann muss ich bis dahin
mit dem Heiraten warten.
Tendré que esperar
antes de casarme con nadie.
Tendré que esperar
antes de casarme con nadie.
Alors il faudra
que je me réserve pour toi.
Allora resterò nubile fino ad allora.
Então acho que vou
ter que te esperar!
Что ж! Тогда буду ждать
и не выходить замуж.
