A former medical technician for Terra Prime who, dying of a stab wound, staggers into an interstellar conference on Earth and hands T'Pol a vial proving that a Vulcan-human baby exists.
Susan Khouri appears at the opening of the Enterprise episode Demons, set in January 2155. She had worked for Terra Prime at its facility on the Moon, where the movement's scientists secretly created a child from the stolen DNA of Trip Tucker and T'Pol.
Horrified by what was planned, Khouri fled to Earth with a sample of the infant's hair. She reaches the talks that will lead to the Coalition of Planets, presses the vial into T'Pol's hand, tells her that they are going to kill the child, and collapses.
Phlox finds that she was stabbed and could not be saved. His analysis of the sample reveals the baby's parentage, and inquiries into Khouri's past lead Enterprise to the Orpheus mining colony and John Frederick Paxton.
