One thing I thought about as coming to the end of reading this part was when did Lucia know that Seingalt was Giacomo? When she first saw him walking from her boat? At the theater? That night at the house before the storm? Or didn't she know until he told the story of the girl he first loved to her?
Now that's a good DQ! I think she recognized him right away, but she doesn't want to reveal herself, so she keeps quiet, wondering when Giacomo will realize it's her. But I think he doesn't remember her at all, she was just a child to have fun with, and she has gone from his memory long ago. And to think she sacrificed herself for his sake (well, that's what I think after reading part 1). We'll see how it goes.
