They actually did it.
The rock of Mystic Falls, and the only grown-up worth keeping around for six seasons, Sheriff Liz Forbes (Marguerite MacIntyre), passed away in tonight’s episode, not from supernatural forces, but from cancer.
Of course, the actress is still alive, and she spoke with press after a screening on Wednesday – revealing that the initial reaction of many is that Caroline’s mother would get better.

“No one thought we’d actually kill her. Nina’s like ‘you’re not gonna really kill the sheriff, right?’ and I was like ‘yeah, we are’,” Julie Plec added, noting that it will make for a good story.
Forbes’ funeral will be in next week’s episode, directed by Julie Plec, and MacIntyre will be back for an open casket. Plec and MacIntyre are longtime friends, and it’ll give them one last chance to hang out in the Atlanta sets.
