Re: How exactly did Clara "save" the Doctor.
The clips of the 2nd and 3rd Doctor are of him running and driving from a teleporation spiral in the episode "The Five Doctors". His 2nd persona runs by Clara, but he is still captured by President Borusa. His 3rd persona drives by Clara and he sees her in his rear view mirror yelling his name but he is also captured by Borusa.
I assumed that although they were taken from The Five Doctors, those scenes aren't meant to be those same scenes. Particularly the Second Doctor, who is now in California with the Eighth Doctor. As for the Third, it could be any random time he was driving Bessie down a highway.
