"Name's Jenny, fell through the Rift from the 61st Century, technically only a couple years old since she was created with a progenitor machine, and not human. The Doctor can clarify her physiology for you. She was abducted by a madman and hooked up to a device, and she was in a lot of pain when we got to her and passed out. Madman claims he channeled the energy of the Rift through her and into himself, and if we assume that's true, she's taken a massive blast of chronons, artron energy, and all the rest from the Rift, you name it."
