014. Snuggling for Warmth
It was supposed to be a quick, fleeting visit to her parents while Rory took a health and safety exam.
The freezing temperatures outside had influenced their decision to head straight home from lunch while her parents visited their local post office. Today she'd, naturally, forgotten her house key. Unfortunately, today was also the day the Doctor had left his sonic screwdriver in his other jacket.
With the neighbours away and the Tardis parked safely inside, the pair had taken to huddling on the doorstep until her parents arrived back home.
She wasn't partially cold; she was wearing what felt like seventy jackets and at some point the Doctor's arm had snaked around her waist, pulling her towards him.
She recons the latter was keeping her warmest.
