Not sure if this is the right place. Also, it's probably been answered elsewhere but I couldn't find it -- if so, please let me know where.
RoW Chapter 88 is almost entirely a continuity error. It's an Eshonai flashback, set to the night when Venli first captures a stormspren in a gemstone. Eshonai knows that Venli has been trying repeatedly to do so, and tonight she finally succeeded.
The continuity problem is from Words of Radiance Interlude I-1 "Narak" This conversation takes place during the day, after Eshonai returns from a successful gemheart run.
So which version is correct? They're both from Eshonai's PoV so it's not a case of unreliable narrator.
