O "artefato" (um navio alienígena de design antigo e indeterminado, possivelmente Voehn) quase certamente não tinha nada a ver com os Habitantes ou seu mítico "Segundo Navio" que viajava de nossa galáxia para outra e depois voltava novamente.
O incidente que levou Taince a se matar (e levar Saluus com ela) foi que, durante sua viagem a este navio antigo, Saluus matou Ilen. Taince suspeitava que Saluus tentava se refrescar com Ilen e Ilen arranhava seu pescoço. Na luta que se seguiu, algo aconteceu e Ilen caiu por cima da borda. A 'peça retorcida de metal' não tem significado especial além do que Saluus presumivelmente a agarrou para se salvar de cair ou possivelmente atingir Ilen.
'Let me explain, in case you still haven't got it: I saw the marks,
Sal. I saw the three red lines on your neck, before you put your
jacket collar up. Remember that? Remember pretending to shiver and
saying, "C-collar," or whatever it was? Remember? Just one of those
little false notes that you don't notice at the time because of all
the fear and adrenalin, that doesn't start to nag at you until long
afterwards. Kept that collar up afterwards, too, didn't you? Kept the
jacket on like some sort of comfort blanket until you could get to a
bathroom and a first-aid kit, didn't you? I remember. And when I was
reaching down to Ilen, I saw her fingernails. With the blood under
them. Saw them very distinctly. Fass didn't; still has no idea, even
yet. But I saw them. I wasn't entirely sure about the marks on your
neck, but then I checked. Remember that last farewell fuck, a couple
of weeks later? Just checking. They were very faint by then, of
course, but they were there all right.
'You always wanted her, didn't you, Sal? Always so desired the
beautiful Ilen. Did you think because she went into the ship with you
she was saying yes? Did you? Did she, then changed her mind? Doesn't
really matter, I suppose. I saw what I saw.
