In the year 5,000,000,000, Jabe had come to see the destruction of Earth from Platform One. Her ancestors were from a tropical rainforest on Earth.
Upon meeting the Ninth Doctor, she took an immediate interest in him. After discovering his true heritage, she felt grief at the loss of an entire species, with him as the only survivor.
