Doctor Who actress Karen Gillan has said her character's relationship with the Time Lord will develop in a surprising way.
The 22-year-old actress stars alongside Matt Smith's new Doctor as Amy Pond, a character befriended as a child by the time traveller before he accidentally abandoned her.
After reuniting with her childhood ally the "Raggedy Doctor", Amy has proved a crucial companion for the Time Lord, helping him steer the course of a futuristic Britain and saving wartime London from the returning Daleks.
Speaking to Metro ahead of Saturday's broadcast of her fourth Doctor Who episode, Gillan said there was a "really interesting dynamic" between Amy and the Time Lord.
"There are many levels to it," she explained. "She won't be following him around like a lovesick puppy. There are some surprises ahead."
Gillan's attractiveness has frequently been mentioned in reviews of the current series and the Scottish actress said she was "flattered" but found it "very weird" to be labelled the Doctor's sexiest companion.
"Doctor Who has a long line of sexy companions, it's nothing new," she added. "I don't particularly aspire to be sexy, I just want to play the part well."
