Shallan Davar

I'm about halfway through Rythm of War right now and My Favorite character is Lift, and my second favorite is either Syl or Maya, I also like Kaladin, Jasnah, Lopen, Rock, Shallan (+ Radiant and Veil), Wyndle, Pattern, Adolin, Renarin, Dalinar, and Navani (not in that order tho). I'm an aspiring author and I'm currently working on a webcomic alongside my fantasy books I will be creating a wiki on here for my webcomic if anyone's interested. The comic is called "The End of The World"

So in chapter 17 " A Pattern" Shallan and pattern are discussing healing and Shallan asks pattern if he knew how she could use storm light to heal. pattern replies that he knows little about why humans break and less about how they "unbreak". Shallan asks if Spren do not break to which pattern says yes but they cannot "unbreak" without aid. I feel like this implies that pattern or at least the cryptids possibly know how to repair or unbreak deadeyes? Unlikely since pattern is convinced at this point he will be killed by Shallan but it really made me wonder. anyone have any insight?

I was reading about Shallan (and her multiple personas) and a thought that struck me was: is Shallan an embodiment of Dissociative Identity Disorder?
