I have a friend with almost identical trauma, and it genuinely hurts me to see how people like him are being bullied.
As it is, the series is very cool.
My friend was one of the best swimmers in the area, he was also quite arrogant. However, he lost all his legs, leaving only tiny appendages.
But now he is the best swimmer in the region in the Paralympic category. Although, as he admitted, it is better to be not the best but healthy than the best but disabled.
