First look at Elizabeth Mitchell on Law and Order: SVU

While her warrior-like V character is fighting to save her only child from evil lizards, Elizabeth Mitchell is also playing another role — one kiddies should fear. The beloved Lost alum guest stars on Law & Order: SVU on March 30 as June, a piano teacher accused of killing a little girl after raping her with a rolling pin. It's pretty heavy stuff, which caused the real-life mom to take pause.

"I had certain things I was and wasn't willing to do — you never actually see anything," says Elizabeth, who played a different child killer on SVU back in 2003. "This is a hard one. You have to do your work, and then leave it behind before going home because it's absolutely toxic."
