At the end of Oathbringer, Hoid grabs a spren (a Cryptic, it seems) from the ruined Alethi palace.
“I know you’d rather have someone else,” Wit said, “but it isn’t the time to be picky. I’m certain now that the reason I’m in the city is to find you.”
I get the strong impression that we’re supposed to know who this spren was meant for, but I can’t figure it out. Surely not Aesudan?
