Samuel brings the carnival to Central Park and plans to bury its audience. Doyle puppeteers Emma into playing her cello and gathering a crowd, but Sylar overpowers Doyle and Peter confronts Samuel.
Hiro meets a 90-year-old Charlie. It turns out time-traveling Arnold ditched Charlie in Milwaukee in 1944, whereupon she got a job and started a family. Hiro is heartbroken, but the adorableness of the Mini-Charlie is such that he decides not to rewrite history just so he and Charlie can be together.
Claire and Noah pursue Samuel to Central Park after Tracy water-drills into their buried trailer and helps them swim to safety. Samuel is exposed as a power-hungry murderer, and Hiro teleports everyone away from the carnival, draining Samuel of his power and leaving him a broken man.
Claire decides it’s time the world knew about people with abilities, and, with a film crew broadcasting the stunt across the nation, jumps off the top of the carnival’s Ferris wheel.
SAMUEL’S ULTIMATE PLAN SPELLS DISASTER FOR THOUSANDS
In the climactic season finale, everyone bands together in an effort to stop Samuel (Robert Knepper) from taking the lives of thousands. Peter (Milo Ventimiglia) joins forces with his most unexpected ally to save Emma (guest star Deanne Bray). Meanwhile, H.R.G.’s (Jack Coleman) life hangs in the balance as he and Claire (Hayden Panettiere) find themselves trapped underground with oxygen quickly running out. Elsewhere, Hiro (Masi Oka) starts to come to grips with the decisions he has made and is called into action to help stop a disaster.
Greg Grunberg, Ali Larter, Zachary Quinto and James Kyson Lee also star. Ray Park, Deanna Bray and Elizabeth Rohm guest star. David H. Lawrence XVII, Harry Perry, and Todd Stashwick also guest star.
Images from the episode after the jump — SPOILER ALERT!
Peter discovers that breaking out of Sylar’s mind is more difficult than he thought. Time moves a lot slower in Sylar’s head than in the real world, so it takes several years in an empty city before Peter accepts that Sylar’s a changed man, at which point the two of them work together to knock down the wall trapping them inside Sylar’s head.
After Lauren stumbles into the carnival and gets her gunshot wound treated, Samuel tells Lauren he’s tired of living in the carnival and hiding what he can do. Then he tells Eli it’ll be the Greatest Show On Earth. Then he tells Claire he’s bringing the carnival to Central Park to make the world tremble before him. Apparently, after 18 episodes of keeping his nefarious plans to himself, Samuel wants to tell everyone about everything.
By way of a Damien Whammy, we learn that Noah was once a used-car salesman (!), that he had a wife named Kate, and that he and Kate were about to start a family when a TK-assisted petty thief killed her. This prompted Noah to become the badass we know today, although it wasn’t until he tracked down and shot an unrelated super that he came to The Company’s attention. After Noah then botched several assignments, The Company tried to restrain his aggression by encouraging him to marry some random waitress. Turns out said waitress was Sandra.
Claire finds this as outrageous as we do, but stands by her father, whereupon Samuel concludes she’s not carnival material and buries a trailer with her and Noah trapped inside.
