The Doctors' Daughter.
Those who don't get the joke... The title of the Doctor Who episode is called "The Doctor's Daughter" and during this episode, some folks copy the 10th Doctor's DNA and create a "daughter" from one parent. Her name is Jenny.
The actress who plays Jenny is the actual daughter of Peter Davidson, who played the 5th Doctor back in the day. She is married to David Tennant, who played the 10th Doctor, and has had a daughter with him. David Tennant's favorite Doctor character growing up was Peter Davidson.
Yeah... it can make your head spin XD
EDIT: Colored and finished the art.
