Rebuilding Babel by the_drifter.

This fic is an unusual premise . . . that Rodney's brain is damaged by a toxin, to the point that he can no longer speak coherently. Imagine Rodney unable to talk!! His salvation turns out to be Sheppard, who's the one who can best understand him.

It has Ronon snorting mashed potatoes, alien religious rituals, an overloading ZPM, and Charlie Chaplin movies as a way of communicating.

(Personally, there's so many fics in this 'verse, that I could never read all the ones that pop up on my flist each day. So recs are very important to me. Hope they're valuable for you, too.)
