'It will,' she replied. '«You» said that to me, this very morning. And when it does, it'll be reflected in the Lighthouse mirror. That's the truth. I'm absolutely certain of it.' ...
'We'll go to Constantinople together. We'll leave tomorrow, eh? What do you say? We'll charter a boat. It's a quick little hop, right across the Mediterranean. Sailing to Byzantium! There was a poem, you know, in my time. Not forgotten, I guess, because they've programmed it into me. All these thousands of years, and someone still remembers old Yeats. «The young in one another's arms, birds in the trees». Come with me to Byzantium, Gioia.' ...
