The following contains MAJOR SPOILERS for the "Fight or Flight" episode of the NBC show, "Heroes."

Veronica Mars! Who's your daddy?

In "Fight or Flight," this week's episode of "Heroes," Kristen Bell, best known for her role as pint-sized sleuth "Veronica Mars," gives an electrifying performance as Elle, an agent for The Company who has ties to Peter Petrelli (Milo Ventimiglia), and who obviously was in his presence at some point. Peter throws lightning bolts. Elle throws lightning bolts and leaves her victims charred and crusty.

Then she calls her daddy, who is very cross with her for not doing things exactly as she was told. (Just please tell me she's not Elle Petrelli!)

Peter finally opens that box! There really is information about his identity inside. His passport, a picture of him with Nathan, and a ticket in his name to Montreal are all in the box. Someone has plans for him, because he obviously couldn't have planned a trip while he was blowing up or being put back together. Before he can explore further, he goes all Isaac Mendez and paints a scene in Montreal, and before he and Caitlin (Katie Carr) can explore what the painting means, they get called to the scene where Elle has left them barbecued Ricky (Holt McCallany).

Matt and Mohinder (Greg Grunberg, Sendhil Ramamurthy) continue to squabble about Molly (Adair Tischler). Molly is in a coma, locked in her own head by the scary nightmare man, aka Matt Parkman's father. Matt learns that in order to find his father and stop him from torturing Molly, he has to go to Philadelphia. A scruffy-but-rakishly-handsome Nathan Petrelli (Adrian Pasdar) insists on going along with him because he wants to find whoever is threatening his mother.

Papa Parkman (Alan Blumenfeld) is in Apartment 9 with the yellow door in Philadelphia. At first, he appears almost simple and curmudgeonly, but turns out to be an even worse Nightmare Man than they imagined. He can mess with people's perceptions and lock them into their worst nightmares. Matt finds himself in prison while Nathan is in post-nuclear New York. Each ends up attacking a tormentor, but Matt realizes they are really attacking each other and is able to end the illusions.

Mohinder in getting sucked into The Company. Desperate to find help for Molly, Mohinder seems to be getting co-opted by The Company, despite warnings from HRG (Jack Coleman). While in the facility with Bob (Stephen Tobolowsky), he is handed a Taser and given his first big assignment for the company. As this is happening, Niki/Jessica (Ali Larter) attacks Bob, and is subdued by newly-armed Mohinder, who comes to realize that she is a prisoner in the facility even though she believes she is there for a cure to the hero-eating virus.

There are superheroes in New Orleans. After mimicking Micah on the piano that Monica Dawson (Dana Davis) claims she can't play, Micah (Noah Gray-Cabey) recognizes what's going on with her and reveals his power to her. The two form a nice bond as a result, and both feel as if they have their powers to serve a purpose.

Meanwhile, back in Japan, Ando (James Kyson Lee) brings some partially faded scrolls from 1671 Hiro (Masi Oka) to a specialist who can determine what was written on them. It turns out Hiro was succeeding in turning Kensei (David Anders) into the hero he's supposed to be in the stories. The relationship between Kensei and Iako (Eriko) is also moving along as in the stories, much to Hiro's stolid dismay. In the last scroll, Hiro talks about the next obstacle the three have to face - fighting an entire army to rescue Iako's father.

What Worked

Almost everything. As we get deeper into the season, the episodes seem to be getting tighter and more engrossing.

What Didn't Work

I'm still not convinced that Peter would be so reluctant to find out who he is. If I was in his position, I would be obsessed with it because if you don't know who you are, it's pretty hard to get on with your life. At least now that Ricky is a crispy critter and Peter has a ticket to Montreal, we know he'll soon be getting out of Ireland.
