I own nothing but the plot
It was a snowy night when the Tardis touched down and when The Doctor got out he was about to swear and curse at the Tardis for arriving at the wrong place and time when he heard a crash and saw a car tumble down the very embankment he was at the bottom of and land several feet away from him where he proceeded to help out the occupant which took several minutes because the driver's door was to badly damaged.
Meanwhile a barley awake Adaline felt herself being dragged from the car and that her rescuer told her that she was going to be Okay and she felt something being placed on her forehead then melting into her skin before passing out.
Once The Doctor patched up Adaline with a spare Mire medikit and was about to take her elsewhere he heard the emergency services starting to arrive he decided to leave Adaline where she was and gave his jacket for protection against the cold and then took of In the Tardis with no one any the wiser with what he just did.
Epiloge
