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...
And I'm sure Anya will be 
happier seeing you smile.
.وأنا واثق أنّ آنيا ستكون سعيدة برؤيتك تبتسمين
Und Anya wird sich auch freuen,
dich lächeln zu sehen.
Si puedes sonreírle a la vida,
Anya también lo disfrutará mucho.
Si puedes sonreírle a la vida,
Anya también lo disfrutará mucho.
et Anya préférera te voir
avec le sourire.
Inoltre, sono certo che anche Anya 
sarà più felice vedendoti sorridere.
E sei que a Anya vai ficar
mais feliz em te ver sorrindo.
Да и Аня обрадуется,
если ты снова будешь улыбаться.
