Young man (The Time of the Doctor)
From Tardis Wiki, the free Doctor Who reference
This unnamed young man was an inhabitant of Christmas during the 300 year Siege of Trenzalore. On the last day of the siege, he came to warn the dying Eleventh Doctor that the Daleks had arrived and that there was nothing they could do. The Doctor mistook him for Barnaby, but falsely assured him that he had a plan. (TV: The Time of the Doctor)
