His trauma manifests in various ways:
* Isolation and distrust: He feels ostracized by society and finds it difficult to connect with others.
* Nightmares: He experiences nightmares related to the train crash.
* Fear of the unknown: He struggles with the realization that he may be something extraordinary and the responsibility that comes with it.
While not a physical injury, the emotional and psychological toll of the train crash is a major driving force in David's journey to self-discovery and acceptance.
