"We will free humanity from its immaturity," he tells Bartosz. The only difference is that in 2019, Noah has a foil. Claudia (Lisa Kreuzer), who was once the director of the nuclear plant, is also recruiting Bartosz. She is making her own time machine. She is also desperate to fix what's been broken. According to Noah, she is evil. He tells Bartosz that there are two groups of people trying to "harness" time travel. She is of the "other" group, and she is apparently more evil than Noah. In this speech, Noah heavily implies that there's something worse than killing kids. (Killing sheep maybe? That also happens in this show.) He and Bartosz might have some blood on their hands when they're done, but at least they're not of the shadows.
