Two friends meet for dinner in a classy unagi restaurant, and get distracted by an apparently young girl who is confidently dining there alone. Somehow, this leads to talk of murder...
So there's no necessity 
for me to do anything.
.لذا لا توجد ضرورة لأفعل أيّ شيء
Ich habe also keinen Grund,
hier einzuschreiten.
No es necesario que haga nada.
No es necesario que haga nada.
Je n’ai nul besoin d’intervenir.
perciò non è necessario che faccia alcunché.
Então não vejo
necessidade de fazer nada.
Поэтому и мне вмешиваться незачем.
