GUYS! I CAME UP WITH A NEW EDDSWORLD/ELLSWORLD AU!! I don't even know if it exists already but blind dancer au.
So basically
Tamara/Tom & paul/Paula are blind on their right

Matilda/Matt, Ell/Edd & Pat/Patricia are blind on their left

Tord/Tori are blind on both eyes

Tori/Tord, Paul/Paula & Pat/Patricia are one dance group

Ell/Edd, Matilda/Matt & Tamara/Tom are one group

So that's the au
