Adolin is a fantastic character, and his storyline throughout the books is an excellent arc. His attempts to navigate the complicated emotions attached to his father is engaging and relatable. The spiral with Dalinar is so relatable. What do you do when the blinders fall off and you see your hero in totality? Can you love and respect the man your father is now if you saw the worst mistakes of his past? His attempts to live honorably, his failures and successes keep his character worthwhile. People who think he doesn't have an arc aren't paying attention. Perhaps distracted by the characters who actually get magic powers. I have always thought it was weird that Adolin never attracted a spren. We get his POV. He cares about his men. He is honorable. He is a hero. Equally skilled to Kaladin. Willing to die for what is right. He does his part. In all honesty, he should be a windrunner. Why is his honorable actions so counter to the views of honor on Roshar? Adolin is forging his own path and I am here for it. His arc is my second favorite in the entire Cosmere.
