MICHAEL: I didn't want you to know I was coming.
Exactly, Apple! And as soon as he said it, he started shouting. Why wouldn't he have let Frankie know he was coming--except to soften him up by scaring him and then letting him off the hook?
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
