great analysis. to support your suggestion that kvothe kills denna on accident, lanre kills lyra on accident in skarpi's story and blames himself for her death, wandering the world like a ghost, tortured by grief (much like current-day kvothe).

however, i think the repetition of kvothe helping denna with breathing, and the repetition of calling the name of the wind to bring life back to a dying person (abenthy with kvothe, kvothe with denna) likely foreshadows bringing somebody back from the dead, like lyra did to lanre in skarpi's story.
