Due South Noticeboard

I've had this image in my head for years, where Dief and Fraser have the ability to swap certain physical senses. Specifically, Dief can "borrow" Fraser's hearing -- and while he's using it, Fraser will be mostly deaf for the duration. And Fraser can borrow Dief's sense of smell. Both sense swaps always happen together -- and neither Dief's manners nor his sense of timing are always what one might wish -- so Fraser can be going about his business and suddenly lose his hearing and be brain-blasted with overwhelming olfactory input (machines, people, perfumes, cleaning products, garbage, all dialed up to 11). And since either of them can initiate the swap without the other's consent, there's opportunity for passive-aggressive sense-swapping and snark as well as considerable humor. At the same time, when they're focused on a purpose -- getting the bad guys, or rescuing some one -- they can be fantastically effective in their teamwork.

I never had a plot to go with it. I just enjoy the idea.
