What do you think of a possibility of Adolin becoming the third Bondsmith? It makes sense to me that if anyone could restore all, or a large number of Deadeyes, it would be Cultivation's Bondsmith. Adolin seems to be interested in helping more of them do what Maya did, and he remains the only major character who isn't Radiant. That would also continue the trend of Kholin becoming Bondsmiths, and of Cultivation manipulating events that bear fruit much later. Maybe she removed Dalinar's memory of Evi in part to make him a more nurturing father to her future Bondsmith. Maya is a cultivation spren as well, so there's a connection there. I'm aware that this is just speculation, but I thought it was fun.
Also sorry if this was already discussed before but I haven't found anything.
