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...
That's it! Hopefully he's a spy! 
Then I can throw him in a cell!
!هذا صحيح! آمل أن يكون جاسوسًا
!سأستطيع حينها زجّه في السّجن
Genau, das ist bestimmt ein Spion!
Dann kann ich ihn einbuchten …
Si es un espía y lo meto en la cárcel…
Si es un espía y lo meto en la cárcel…
Ah, si c’en est un,
je pourrai le coffrer…
Giusto! Dev'essere una spia!
In tal caso potrò sbatterlo in cella!
Já sei! Espero que
ele seja espião!
Точно! Вот бы шпионом
 оказался! Посадил бы его!
