Niki died in a fire during the season two finale of Heroes.

That much is true.

But new Heroes spoilers reveal that Ali Larter will, indeed, be back for the third season of the show. Niki, however, will not.

Not much is known about Larter's new personality, but her name will be Tracey Strauss. We've learned that she'll work closely with the Governor of New York, played by Bruce Boxleitner. Just how closely?

This grainy photo should give you an idea:

Indeed, Tracey is rumored to be the Governor's mistress. She'll reportedly have no recollection of her prior life and will work closely with Nathan to get him involved in the government.

But won't Nathan remember her as Jessica, the woman he slept with in Las Vegas? Guess we'll need to tune in and find out!
