Maiara Walsh has signed on to be killed off The Vampire Diaries. At least that's what it sounds like.

The 22-year old actress, best known for her role as Gaby's niece on Desperate Housewives last season, will guest star on the October 7 episode of this CW hit.

As told to TV Guide Magazine by producer Kevin Williamson, Walsh will portray a Mystic Falls high school student who "sets her eyes on Jeremy and encourages him to party it up at the Lockwood house."

Hmmm... based on what we know about the focus on the Lockwood (i.e. werewolf) Curse this fall, along with Jeremy's luck with women, we don't foresee Sarah sticking around beyond one episode.

The Vampire Diaries, meanwhile, kicks off its new season on September 9. That's just over a week away!!!
