An oddball, Carbon is much more shy than his kin. He tends to stick close Leon and is generally wary around everyone else. He doesn't dislike company! The little Meridhi is just used to the group being limited to Leon and himself. Despite the shyness and his hestitancy to leave Leon alone Carbon is self-sufficient - like most of his kind he's highly intelligent and capable of adapting to his emviornment.

The duration of their friendship being wahat it is and Carbon's understanding of Leon's condition puts him im the perfect position to help. The Meridhi has become a postman of sorts and delivers goods and letters from Leon to their destinations. As long as the little guy has clear imstructions he's more than capable.
