when does the doctor gave rose his clone
Journey's End (Doctor Who) In the dénouement of the episode, the Doctor parts ways with his companions: Sarah returns home to her son Luke; Martha and Mickey leave with Jack; and the Doctor returns Rose and Jackie to the parallel universe they were trapped in, in "Doomsday". The Doctor has the other Doctor stay in the parallel universe for committing genocide and to requite Rose's love, since the second Doctor is part human. That means he has only one heart and can't regenerate, and will grow old and die along with Rose. After departing, Donna's human mind becomes overwhelmed by the Time Lord knowledge and starts to deteriorate. To save her life, the Doctor is forced to wipe her mind against her wishes, and explains to her mother, Sylvia (Jacqueline King), and grandfather Wilfred Mott (Bernard Cribbins) that Donna must never remember him or anything that they did otherwise she will die. As the Doctor leaves, Wilfred promises that he will never forget the Doctor on his granddaughter's behalf.
