I'm confused about the Grounder language in The 100. It's been 100 years (more or less) since the nuclear apocalypse, yes? How did the Grounders' language change so fast? I mean, the branches of Vulgar Latin took 300-400 years to go from "dialect" to "distinct language," so I would think that after 100-ish years, the Grounders would still only speak heavily-accented dialects of American English. Am I missing something?
