10 TV Characters Who Disappeared Without A Trace

5. Half The Cast Of Boy Meets World - Boy Meets World

This sort of thing happens every few episodes on Boy Meets World, so it's best not to get too attached to anyone. And it's not just one-off characters, either, that we don't really need to see again -- it's close friends and familial connections that should have been a part of the canon continuity.

For example, how many of you remember that Topanga once had an older sister named Nebula, only to somehow become an only child? Or that over the years, Shawn has had three different siblings, only one of which has stuck (Matthew Lawrence as Jack). He had an older sister named Stacey very early on in the series, and an older brother who he caught stealing on camera. We can only assume that these two ragamuffins fell into an open sewer or something for the duration of the show, because Shawn seemed to forget about them.

Then there's Mr. Turner, who has a pretty substantial story line as Shawn's pseudo-adoptive father. It ends after a serious motorcycle accident with Shawn praying at the foot of an unconscious Mr. Turner's hospital bed. They close out the episode with Mr Turner's fate remaining ambiguous, and then they never bring it up again. Come on. You can't do that! We don't ever see Mr. Turner again, and Shawn never even mentions the man who was kind enough to take him into his home when he needed it. Which makes it pretty clear that Boy Meets World just straight up did not care about continuity.
