Even if you’re unfamiliar with Sister Wives, chances are you’ve seen Kody Brown’s infamous blonde curls. The TLC series is now in its 19th season, and much has changed since its debut over a decade ago. Originally centered around Kody’s polygamous family with four wives—Meri, Janelle, Christine, and Robyn – only Robyn remains in recent seasons, as the other three have left the plural marriage under tumultuous circumstances, all unfolding on national television.
