3. He No Longer Has The Looming Threat Of Trenzalore
BBCIn 'The Name of the Doctor' we saw Matt Smith's 11th Doctor become quite terrified at the thought of Trenzalore. This mysterious planet was, in one time line at least, the location of the Doctor's grave. We also see in 'The Day of the Doctor' that both Smith's and Tennant's Doctors are afraid of Trenzalore and what might ensue when he eventually travels there. Now that 'The Time of the Doctor' has wrapped up this story, however, the Doctor no longer has to worry about what he always thought would be his final battle.
