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...
Not to mention, I don't think this 
was really a financial issue...
...هذا دون ذكر أنّني لا أراها مشكلة ماليّة
Zudem glaube ich nicht, dass die Finanzen
bei uns das Problem sind …
Y tampoco tengo muy claro
que esa cantidad sirva de mucha ayuda.

Et je n’ai pas l’impression
que c’est une question d’argent.
Inoltre, dubito fortemente che 
si tratti di una questione finanziaria...
Sem falar que não acho que
seja um problema financeiro...
Опять же, что-то мне подсказывает,
что дело далеко не в деньгах…
