A question for "Heroes" fans...?

Ok so it's been leaked that Tracy Strauss actually survives her "murder" in the parking Garage after being shattered into bits and pieces (It should of been obvious considering that it shows the piece of ice that was part of her face blinks and drops a tear.) So anyways, Tim Cring, the creator of Heroes states that when Tracy comes back, she'll fight for the good guys and also stated that Season 4 is going to have a big Tracy vs. Barbara story, the third sister of the set of triplets...That would mean that Barbara is going to be a bad guy, so what do you think her power will be? Tim Cring never mentioned Barbara's power but most people speculate that her power is going to deal with something mental due to the fact that Niki's power was physical and Tracy's power dealt with her environment. I think that Barbara's power is gonna probably be the manipulation of probability fields like Black Cat from Spider man or Domino from the X-men. What do y'all think?
