Doctor Who Profile: The Eleventh Doctor
The Eleventh Doctor is whimsical and energetic, but also brooding and manipulative. His number one rule for his Companions is that the Doctor always lies, which takes the sneakiness and deceitfulness the Seventh Doctor to another level. Though he initially feels out of place with humans, not understanding basic elements of social interactions, the Eleventh Doctor eventually becomes downright domestic (in his way) with River and, after his relationship with her progresses and she heads to the Library, he becomes quite leery in his interactions with his female allies and Companions. He’s impatient and easily bored, struggling to sit still at any given moment while valuing stability for his Companions in a way he hasn’t previously and traveling with Companions who have (comparatively) normal home lives separate from their multiple-story adventures with him.
