Such an interesting concept to consider. Of course there would be innumerable challenges since so much of the magic in Harry Potter is visual. Transfigurations could be as much of a problem as Potions. How will she know if her spells have been successful or not without viewing the result?Originally Posted by OliveOil_Med
Probably like normal blind people she would develop her senses of hearing and touch more to compensate for the lack of sight. Perhaps there are even special spells for that purpose that professors would give her individual training in. Ron mentions a Supersensory Charm in the epilogue of Deathly Hallows, the Homenum Revelio spell might have variations she could learn, and maybe the Point Me spell could be used with an added destination command. I'm sure she would not want to feel completely dependent on a seeing-eye elf her whole life.
So many other interesting questions come up. What would her Boggart be if she can't see it anyway? What would her Patronus be if her she has never seen an animal for her magic to create an image of? Could she learn to perform Legilimency and 'see' in that way when she reads someone else's thoughts or memories? I think you have a gold mine of possible storylines, Molly.
