I just saw Chi l'ha visto. Now we know that the cctv shows AC already throwing up when he was coming out from the tube station. (The friend who was waiting for him at the platform explained that he saw the cctv and he saw that Antonino was already vomiting). Why didn't he go back to the tube platform? Did he get embarrassed about people watching him throw up? Everyone is different but I wouldn't care to throw up in the middle of the street or outside a station if I was feeling sick and especially in London...who cares if people stare at me or what people think.
