Kaine has a VERY rare form of dwarfism and has missed out on being a normal kid because of his condition - Brachytelephalangic Chondrodysplasia Punctata Or (CDXP1).
When he was 3, he was critically injured which changed the path of the life he had, permanently disabled due to a negligent caregiver.
Kaine has had a spinal decomposition and a spinal fusion from C2 to C7, effecting his movement permanently, requiring multiple surgeries and lengthly stays in hospital.
