The switcheroo has been revealed, and now the ghosts of the past must be laid to rest.
You squeak by without even
a faint understanding of the case.
.تثرثر دون حتّى أدنى فهم للقضيّة
Du hast dich durchgeschlagen,
ohne die Hintergründe zu verstehen.
Le dossier t’échappe,
alors tu temporises.
Sem entender o mínimo do 
caso, você dá um jeito.
Лезешь в дела, совсем их не понимая.
