Hey, aren't you supposed to be a little 
more subtle about assassinations?
Hey, sollte ein Attentat
nicht heimlicher ablaufen?
Oye, ¿no deberían ser más 
sutiles con los asesinatos?
Vous n’êtes pas très discrets,
pour des assassins.
Ehi, non dovresti stare
 un po' più attento agli assassini?
Ei, você não deveria estar mais
 prevenido contra assassinatos?
Тоже мне. Для убийц вы действуете
уж слишком открыто.
