Edited the power discussion part to show the blindness leaves when Devin breaks concentration. 

I understand the dog thing. I might be a little close to this situation since I work with blind people often and have been a volunteer trainer for seeing eye dogs for several years. I understand you might not know a lot about the difference, but for a blind person who is going to a completely new place having a dog is a much better situation as the cane only tells you what is in front of you whereas a dog can assist with commands like "food" and would take the owner to a specific place like a kitchen or cafeteria. 

The cane isn't a big hiccup, but it will require my character to constantly ask where he is or where something is for a large amount of the role play. Would it be acceptable to say that the school isn't allowing him to bring a dog and maybe it is something he is upset about?

 Also when you talk about insurance and things like that the government (speaking of USA right now and Korea and Viet Nam since I have experience there.) actually has tax deductions for making a place more disability friendly and that includes returned funds from insurance companies and construction firms.
