Barney (Deep Breath)

Barney was an elderly human with a disheveled appearance encountered by the newly-regenerated Twelfth Doctor.

Barney was roaming a back alley of Victorian London with a glass bottle in tow, where he found the Doctor rummaging around in garbage and filth for clothes. Barney was taken aback by the highly erratic behaviour of the Doctor as he suffered from post-regenerative trauma. Barney tried to play along with the Doctor's whims. He recoiled at the sight of the Doctor's face and steered clear of him as best as he could.

The Doctor decided that because he was cold, Barney should give him his coat, though Barney himself was cold. Barney refused to do so until finally being offered something of greater value. He swapped the Doctor his coat for his favourite watch, along with a set of worn out fingerless knit gloves. (TV: Deep Breath)
