Biography
When Cline saw that the Doctor's hands were clean he forced him to process his DNA in a progenation machine, thus creating Jenny, the Doctor's daughter. Both Cline's father and grandfather fought the Hath.

When Cobb put the Doctor, Donna and Jenny in a cell to prevent them from stopping his attempt to reach The Source. Cline was given the job of guarding them. Jenny tricked him into opening the cell by kissing him through the bars and stealing his gun. Cobb later found Cline tied up, gagged and embarassed; Cline then joined the search for the Source. After Jenny's death, Cline asked the Doctor to help them give her a proper ceremony.

After the Doctor, Donna and Martha left, Cline, alongside Hath Gable, bared witness to the mysterious resurrection of Jenny. (DW: The Doctor's Daughter)
