Hey everyone this is my first theory, it’s a pretty straightforward one. I apologize in advance if this has been discussed before. Alright it’s all based on this scene.
Chapter 83 page 1003
“Storms” the surgeon said, “Highprince, you’re all scars under here. How many time have you been wounded in the shoulder”
“Can’t Remember”
“How can you still use your arm?”
“Training and practice”
“that’s not how it works…” she whispered eyes wider “I mean… Storms…”
So my theory is that Dalinar got crippled and went to the Nightwatcher to be healed.
Also after he bond with the Stormfather he breathed in stormlight and “he felt his wound healing in a familiar way, He’d done the before."
The Nightwatcher healed him with stormlight.(see straightforward )
So what do you think?
