That finale features a good twist at the very end, as Ciro, with Genny's help, kills Pietro (Genny's father). This season was aired in the UK last year, and the ending evoked a lot of criticism.

Did Genny kill Pietro?

With the pistol that Gennaro gave him, he shoots Don Pietro in the head, killing him.

Who killed Pietro Savastano?

Season 2: The era of the Savastano clan, that once undisputedly reigned over Naples, seems to be hopelessly over: the clan's godfather Pietro Savastano has lost his mind behind bars, his wife Imma and son Genny shot by Pietro's own former right-hand man Ciro.
