So we know that Sak's ability to forsee possible deaths for Dusk is unique, as Vathi tried bringing other ravens but they didn't get the same ability. Could it be that Sak got this special ability because he was the second nahel bond for Dusk? I think this may be the case because Shallan bonded both Pattern and Testament and has the ability to access fortune while drawing, so I thought a similar thing may be happening with Dusk and Sak. Apologies if this has been posted before.
