If you're entering on an EU passport they are not allowed to ask you any questions about the purpose or duration of your visit (as you're entering as a matter of right, not privilege). And Immigration really have no way of knowing where someone has just flown in from, unless there have been no other arrivals... so as far as they are concerned it's just a case of an Italian entering the country, it doesn't matter where from.
(I've occasionally been asked where I've just arrived from, but that was usually when I was one of the first people off the aircraft and it seemed to be more a case of Immigration wanting to establish which flight they dealing with with rather than wanting to know where I had just been)
