Television characters disappear all the time, but usually somebody bothers to explain where they went. They move away, change jobs, get divorced, or receive some suitably dramatic exit. Then there are the unlucky ones who simply stop existing. A sibling heads upstairs and apparently never comes back down. A White House staffer vanishes between seasons. A teacher survives a serious accident only for the show to lose interest in what happened next. There is even a name for this particular kind of television amnesia: “Chuck Cunningham Syndrome”, after one of the most famous missing sitcom characters ever. Here are 15 times a show seemingly forgot it had introduced a character in the first place.Redditcnx.cmd.push(function() {cnx({playerId: "106e33c0-3911-473c-b599-b1426db57530",}).render("0270c398a82f44f49c23c16122516796");});Chuck Cunningham Basically Invented the ProblemRichie and Joanie originally had an older brother on Happy Days, but Chuck disappeared after the early seasons and was never properly explained, with Howard eventually referring to having only two children.IMDbJudy Winslow Went Upstairs and Never Came BackJudy was one of the Winslow children for four seasons of Family Matters, until she was sent upstairs in one episode and simply never returned or received another mention.IMDbMandy Hampton Apparently Left the White House Without Telling AnyoneMoira Kelly’s Mandy was a major presence throughout the first season of The West Wing, only to vanish entirely when Season 2 began without an onscreen departure or explanation.IMDbDonna Had a Sister Until She Suddenly Didn’tTina Pinciotti appeared as Donna’s younger sister during the first season of That ’70s Show, then disappeared as the series decided Donna worked better as an only child.IMDbThe King of Queens Misplaced an Entire SisterCarrie’s half-sister Sara Spooner appeared repeatedly during the first season of The King of Queens, then disappeared without explanation and was never folded back into the family story.IMDbBetsy Apparently Stopped Working at the Office OvernightZoe Jarman’s Betsy Putch was part of the regular office ensemble on The Mindy Project, but between Seasons 2 and 3 she vanished with no real explanation from the characters around her.IMDbBones Sent Dr. Goodman Away and Forgot to Bring Him BackDr. Daniel Goodman ran the Jeffersonian during the first season of Bones, but after stepping away from the job, he never returned to reclaim his position or complete his storyline.IMDbMinkus Spent Three Years on the Other Side of the SchoolMinkus was a major part of Boy Meets World Season 1 before disappearing for years, only to return at graduation and jokingly claim he had simply been elsewhere in the school.IMDbThe Golden Girls Had a Live-In Chef for Exactly One EpisodeThe pilot of The Golden Girls included Coco, the women’s live-in chef and housekeeper, but the character was dropped immediately once the show settled around Dorothy, Rose, Blanche, and Sophia.IMDbEven the Brady Family Dog Got ForgottenTiger was the Brady family’s dog early in The Brady Bunch, but after the original animal died and a replacement briefly took over, the character eventually disappeared from the series without explanation.IMDbMad About You Lost Paul’s Best FriendSelby appeared throughout the first season of Mad About You as one of Paul’s close friends, then vanished after Season 1, something the show eventually joked about years later.IMDbStar Trek Quietly Removed Janice Rand From the EnterpriseYeoman Janice Rand appeared prominently during the beginning of Star Trek, including a developing connection with Kirk, before disappearing halfway through Season 1 without an in-universe explanation.IMDbMAS*H Never Told Us What Happened to Ho-JonHo-Jon regularly helped Hawkeye and Trapper during the first season of MASH*, but after appearing several times, he simply stopped showing up and his future was never addressed onscreen.IMDbThe Facts of Life Started With Way More Girls Than Anyone RemembersThe first season introduced seven Eastland students, but Cindy, Sue Ann, Nancy, and Molly were largely phased out when the show retooled itself around Blair, Natalie, Tootie, and newcomer Jo.IMDbMr. Turner Survived a Motorcycle Crash, Then Basically VanishedAfter a major Boy Meets World episode left Mr. Turner recovering from a serious motorcycle accident, the teacher stopped appearing, with only a later joke suggesting he was still somewhere around campus.The post 15 Times the Writers Literally Forgot About Their Character appeared first on Den of Geek.
