Biography
In the year 5 Billion, Jabe had come to see the destruction of Earth. Her ancestors were from a tropical rainforest on Earth.

Upon meeting the 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.

When Platform One came under attack, she sacrificed her life valiantly, staying behind to allow the Doctor to fix the sun filters. She burnt to death under the immense heat. (DW: The End of the World)

The Doctor recalled Jabe, along with others, when Davros made him think about all those who died in his name. (DW: Journey's End)
