Ten/Donna Doctor tells off Sylvia
The Doctor and Donna have been traveling together for awhile, but no matter how many times The Doctor tells Donna that she's brilliant, or smart, or beautiful she won't believe him. She just keeps thinking of herself as a fat Ginger with no real skills except for her typing. The Doctor finally figures out that it was Sylvia and all of her constant put downs of Donna that damaged her self confidence so badly. I'd like to see The Doctor try to fix this by going back in time to tell Sylvia what she's doing to Donna. Where in Donna's timeline should he go? Will it make any difference? Will Sylvia change how she treats Donna?
