Fan fave Elizabeth Mitchell, who was nominated for a 2010 Emmy for her portrayal of Lost's tragic Juliet Burke and is now kicking lizard butt on ABC's V, has been signed for a horrifying guest role on NBC's Law & Order: SVU.

She'll be starring alongside returning guest star Jeremy Irons, who appeared earlier this season as the colorful Dr. Cap Jackson. Elizabeth will play an unmarried piano teacher who was the last person to see one of her students alive.

While SVU has tackled some unsettling topics during its twelve seasons, this one may take the cake — and win Elizabeth her first Emmy. For the first time, the series will deal with a case in which a woman is suspected of sexually assaulting and murdering a child.

Because of the rarity of this offense, Dr. Jackson is called in to consult with Benson (Mariska Hargitay) and Stabler (Christopher Meloni) because he has studied women who have committed this heinous type of crime. The shocking episode, titled "Totem", is scheduled to air March 30.

So Lost/V fans, how do you feel about our little Miss Juliet engaging in something so horrifying? Excited to see this? Or would it forever cloud your image of Sawyer's idyllic love?
