"Didn't take!" said by both Peter and Claire.

When have you noticed repeated quotes in Heroes.

Yeah, I've noticed they do recycle quite a lot of their lines, as well as make references to some of their older episodes. They also use the word 'hero' or some variant of it frequently. It's cool to see how it comes full circle, but sometimes it seems like they re-use lines because they've backed themselves into a corner writing wise, but I think they intentionally do that so it's all connected.

Claire said din't take in Homecoming, Peter said it in How To Stop An Exploding Man
