Pea is depicted as a loyal and brave character, yet he fails to learn from his past experiences despite having faced many situations. His repeated mistakes highlight a lack of awareness and understanding of the dangers around him. For instance, he consistently approaches a horse known for kicking from the wrong side, only to be shocked when he gets hurt.

This pattern of behavior not only showcases his bravery but also his inability to adapt or learn from consequences. Pea's experiences could serve as lessons, but he remains oblivious to the risks, reinforcing a theme of stubbornness and the limitations of personal growth within the narrative of "Lonesome Dove."
