First time poster. I just finished Oathbringer (no spoilers in this thread), and it got me thinking back to Edgedancer. As far as I can tell, Nightblood's personality is usually driven by a need to kill/destroy evil. Although I have not read Warbreaker, I do have the Nighblood dialogue in Oathbringer to base this off of. The need for destruction made it seem very odd to me that Nightblood "liked" Lift in Edgedancer. I do not believe Nightblood indicates he likes anyone else, perhaps Szeth (but even then not directly), in Oathbringer. So my question is why? Why does Nightblood like Lift? I did a search and couldn't find an answer so I thought I would post. My only semblance of a theory is the fact that Lift has a stronger than normal presence in the cognitive realm, but I do not know why that would make Nightblood like her. Anyone else know of something I have missed, or perhaps have more insight into Nightblood's motivations from reading Warbreaker?
