I was wondering if anyone knew of any gen/het fireman!Dean fics?

More general, any gen/het fics where Dean and Sam are not hunters? Or one is and the other isn't? I'm also searching for gen/het fics where Dean and Sam are raised apart (but still brothers).

Lastly, I'm looking for multi-chapter fics where Dean (or Sam) is mute, deaf, or blind. But not born that way. I've read a bunch of one shots with such a theme but I'd like something that I can really dig into.

Thank you so much for any help! :D
