When Callahan was an infant he had congenital blindness. Due to a severe infection in his eyes he almost died, though he’s almost completely blind and can only see light. He is 24 years old. Most of the time he has his eyes closed since he never used them. He’s a very caring and kind person. He’s very soft spoken and never speaks loudly. He’s suffered from depression but he’s been a lot better since he’s gotten out of highschool.
