Fair warning: this post contains a Modern Family spoiler.
Whether or not it's a major spoiler is a matter of some debate.
Modern Family's co-creator promised that, in Season 10, a character of significance would die.
On Wednesday night's episode, that happened ... sort of.
See (and here's the spoiler), the "major character death" was DeDe, Jack's ex-wife, the mother of both Mitchell and Claire.
DeDe is not a main character -- she's just related to a bunch of them.
She did not appear in even a guest role in Season 3, Season 5, or Season 6.
Modern Family fans took to Twitter to express their outrage over all of that hype having been built up for nothing.
