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...
Looking closer, this is clearly 
not the raccoon cipher.
بعد إعادة النّظر، واضح تمامًا
.أنّ هذه ليست شيفرة راكون
gar nicht die Tanuki-,
sondern die Raupen-Verschlüsselung!
Es verdad, no es cifrado mapache,
¡es cifrado gusano!
Ahora que me fijo, no es cifrado
mapache, ¡es cifrado gusano!
C’était pas un code Raton laveur,
mais un code Chenille !
Guardandola meglio, non usa il codice Procione,
Olhando bem, não é a cifra guaxinim.
Это ж никакой не енотий шифр!
Чёрным по белому — гусеничный!
