Continuing my extremely irregular feature here at the prattle, it's time once again to crack the books on the Witless Dictionary: an ongoing attempt to come up with words we don't have, but should.
And yes, I know that's exactly the same thing as "sniglets." Only mine are far dorkier and, as such, of far less interest.
Mystery Collapse Disorder--Term given to define the precise moment when a character for whom an aura of mystery has been carefully cultivated ultimately collapses into irrelevance under the weight of accumulated mysteries layered one on top of the other until any intrinsic qualities the character has are utterly buried under layers of "secrets," "clues," "shocking revelations," and other kinds of bafflegab.
Or, to be blunt, the point at which the viewer/reader can no longer keep track of what the hell the deal is with the character, and doesn't really care that much.
Noted sufferers include Wolverine, Cable, Gambit, and Professor River Song.
