Kaladin and Shallan face complex mental health challenges. Their journeys illustrate the difficulty of simultaneously managing internal wounds and coping with societal failures to care for the mentally ill.

Since his brother’s death and his enslavement as cannon fodder, Kaladin has had bouts of depression, suicidal ideation, and even the urge to die by suicide. At first, external validation lessens Kaladin’s symptoms: The lightheartedness of Syl, the spren he bonded, helps him overcome some depressive episodes, while protecting fellow bridge runners and warriors allows Kaladin to feel useful, keeping his symptoms at bay. Moreover, friends and allies reassure Kaladin and attempt to support him. Dalinar, when removing Kaladin from active duty, comforts him: “Don’t be ashamed, son. […] That sort of experience leaves scars, same as any wound. It’s all right to admit to them” (147). Adolin drags Kaladin out and surrounds him with good company, providing a caring presence and ensuring that Kaladin does not give into complete isolation: “You don’t have to smile. You don’t have to talk. But if you’re going to be miserable, you might as well do it with friends” (166). Syl commiserates with Kaladin: As she begins to remember her old Knight Radiant, however, she recalls her grief over his death, which lets her understand the darkness Kaladin feels.
