Hiro and Ando are back in the past, and they decide to go see Mystery Sock to figure out what they're supposed to do. Peter begs Claire not to go to Paris because she's supposed to save the world. He tells her that he's going to explode and that she's somehow a part of all this and if she leaves, maybe some bad stuff will happen. Parkman, Bennet, and Sprague are still traveling together across the country, heading for New York.
Sylar paints himself stealing Ted's power and realizes that this makes him the exploding man. He decides to call his mother and then go pay her a visit. Hiro and Ando show up and almost get caught by Sylar, but they teleport out just in time. Sylar heads off to see his mom, and Hiro and Ando follow him so that Hiro can bust out the Sword of Destiny and finally off the psychopath. Thompson hooks up with Mohinder and invites him to meet little Molly Walker, a child with the ability to find anyone, anywhere, but who also happens to be very ill with the same disease that killed Mohinder's sister. Thompson wants Mo to cure her because she's the only person on the planet who can find Sylar. Mohinder does find a cure for her, and a new friendship is born.
D.L. and Jessica are having all sorts of issues with each other, so they decide to phase into Linderman's office in search of clues as to Micah's whereabouts. They find out that Linderman basically orchestrated their entire lives and that they're one big science experiment, with Micah the ultimate conclusion. Peter learns that Claire knows an exploding man of her own, Ted Sprague, and they ask Nathan to track him down just in case Ted's the bomb instead of Peter. Nathan agrees, but as soon as Peter and Claire leave, he totally reaches out and touches Linderman. Later on, Claire and Peter go to visit Nathan's office and see that he's talking to Thompson. Claire decides then and there to get the hell out of town, regardless of what Peter wants her to do.
Sylar visits his mother, and she's just about as batshit as he is. He wants to stay with her so that he can avoid killing millions of people, but after he shares his special powers with her, she freaks the hell out and tries to stab him with some scissors. Unfortunately, she winds up stabbing herself. Hiro shows up to kill Sylar, but somehow Sylar can resist the time freeze, and he scares the bejesus out of Hiro when he grabs the sword in one hand and orders Hiro to kill him. Hiro chickens out, of course, and Ando shows up to distract Sylar so that Hiro can teleport them out of there. Hiro's sword is broken in half, however, so it looks like killing Sylar will be harder than they thought.
Peter tries to convince Claire that she should stick around so that she can shoot him in the head in case he starts to explode. Claire's not fond of this idea. Ma Petrelli visits Nathan and pretty much gets him to agree to follow through on the Linderman plan. Peter and Claire go to a spot that Peter saw in his visions so that they can possibly meet up with Sprague. Sure enough, Bennet, Sprague, and Parkman show up, and Claire and her father have a mini-reunion. Too bad that Peter starts absorbing Ted's power and can't control it. The show ends on a "Will he or won't he?" note that's really silly because, hi, we all watched the previews, NBC! We know he doesn't explode THEN.
Previously on Heroes: It was five years in the future, and Sylar was Nathan and Peter was hot and Parkman shot Future Hiro and Peter blew up and killed a bunch of people, including Micah, and Niki was really sad about that so she got on the pole to take her mind off it and the whole world, in general, was fucked.
But now Hiro's back in the present, and he and Ando are going to save the world. Again. Some more. They're back on the Superroof, talking about how they can change the future. Hiro opens up The Last Comic and mentions that it hasn't been finished because the character's dialogue hasn't been filled in. Hiro gets the bright idea to go ask Mystery Sock what they're saying in the final pages. Yes. When in doubt, go to Mystery Sock. Hiro stands up on the ledge and announces to New York that they're going to save it. New York promptly tells Hiro to shut the hell up.
Petrelli Palace. Peter's sitting off by himself in some corner, sketching bleak visions of the future in a little book. Nathan's wife and two kids return home after an extended trip to Unnecessary Characterville and he gives them all hugs and kisses while Claire watches from a hidden perch on the stairway. She clearly wishes Nathan would show her the same fatherly care he shows his other children. Peter notices her watching and looks at her with sympathy.
Later on, Mama Petrelli helps Claire pack while Claire twists her hair around her fingers and generally hates on the whole "exile to Paris" idea. Shut up, Claire. It's Paris. PARIS RULES. Just go there, order un cafÃ© et une croissant and try not to get autopsied or anything. Peter enters and Mama Petrelli leaves them alone to say their goodbyes. Peter doesn't want Claire to leave, but she says she has to. Peter thinks that their meeting and her winding up being his niece aren't just random; it's destiny. He says that she's here to save the world and Claire's like, oh not THAT again. Peter tells her that this isn't some fantasy; he's seen the future and he knows that he explodes and wipes out the whole city. "Like a nuclear bomb," he says. "Nuclear?" says Claire. "Like Ted." "Who the hell is Ted?" asks Peter.
Funny you should ask, Peter! Ted's this guy with radioactive hands, and he's currently in the great Midwest with Bennet and Parkman, heating up the roof of a used car. Parkman tries to call his wife from a payphone, but Bennet quickly puts a stop to that, saying that they can't contact their loved ones for fear of the OWI getting a hold of them. He talks about the new tracking system they're using at the Company; it's called the Walker System and it doesn't rely on isotopes and satellites. "It just finds you wherever you are," he says. Therefore, they have to play it smart and switch cars a lot and stay on back roads. Matt understands that they have to go to New York and wipe out the Walker System. They go to the car Ted's working on, and Ted uses his handy spark plug hands to start the car. "Let's go," he grits at Bennet.
Cut to Sylar in the Superstudio, painting a picture of Ted. The image on the canvas seems to be Sylar threatening Ted, so Sylar thinks this means that he steals Ted's power and becomes the bomb and blows up New York. Oddly, Sylar doesn't seem too happy about this. Switch to Suresh in the Biggest Apartment in Brooklyn. The phone rings. Mohinder picks it up and it's Sylar. He's freaked out. "I think I'm gonna do something bad," he says. Mohinder's like, "'GONNA'? Oh, right, because killing dozens of innocent people isn't really evil or anything. What constitutes 'bad' in your book, psycho?" Sylar says he thinks he's going to kill a lot more people and, unlike his other killings, which, in his twisted mind, he thought had purpose, this mass killing he's going to potentially partake in will be a massacre of innocents. There's nothing to gain from this genocide, so Sylar's not sure why he would do it. Mohinder tries to keep Sylar on the phone while dialing 911 on his cell and Sylar's like, dude. I CAN HEAR YOU DIALING THE PHONE. Sylar hangs up the phone and stares at the painting of his potential future as the Bomb That Ate New York.
