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...
Are my failures that amusing to you?!
!هل فشلي ممتع في نظرك لذلك الحدّ؟
Freust dich wohl,
dass ich mich so blamiert hab!
Ti diverte tanto
 questa mia magra figura?!
Meus fracassos são
engraçados para você?
Настолько потешна моя неудача?!
