In "An Invisible Thread", Claire and Angela are shown to have escaped Noah's vehicle just before the car is swarmed with agents. Claire meets up with Nathan, and is instantly suspicious of his identity, especially when 'Nathan' fidgets with Noah Bennet's necklace. Claire's suspicions are confirmed when 'Nathan' starts taking control of her body and reverts into Sylar. Sylar then takes on Claire's form. When Noah calls her, Sylar/Claire answers the phone and tells him that Nathan is indeed Nathan, only to revert to himself and taunt Noah. Sylar then attempts again to sway Claire to his side of things, and lists things they have in common (both were adopted, both can't die), and taunts that Claire will grow bored of trying to kill him. He flings Claire out of the room just as Nathan and Peter arrive. When the Petrelli brothers go to battle Sylar, Claire is locked out of the room. After things quiet down, she enters the room to find it a mess, and Peter flies in. Claire and Peter go to search for Nathan and Sylar, only to run into an armed Noah, who wonders if Claire is Sylar in disguise. Claire proves it's really her just as agents hold them at gunpoint, and since they don't believe Noah's suspicions about Sylar, Claire saunters up to the guards and threatens them. That night, Claire, Noah, Matt, Hiro, Ando, 'Nathan,' Peter, and Angela are gathered around a burning centerpiece as they watch the cremation of "Sylar."
