Tim Latimer

Tim Latimer was a young schoolboy in 1913.

Biography
Tim attended Farringham School for Boys in 1913, which allowed the fob watch that contained the Doctor's Time Lord essence in it to communicate with him and instruct him. It was able to do this because Latimer had low level telepathic abilities, that it could access. This also granted him a vision of the First World War, which he used to escape a shell at a critical moment. After the Family of Blood was defeated, the Doctor let Latimer take his watch to look after and give him good luck. He fought in the First World War and survived. Like the Doctor he did not like violence and refused to use a gun when the Scarecrows attacked responding to a call of "Coward!" with "Yes sir! Every time!" an echo of the Doctor's answer to the question "Are you Coward or Killer?"

Many years later, the Tenth Doctor and Martha Jones saw him again as an old man as a veteran at a Remembrance Day ceremony. By which point he was apparently wheelchair-bound, but still recognised them and silently acknowledged them, with tears in his eyes. (DW: Human Nature / The Family of Blood)

Earlier in the same season he bumped in to Martha Jones and recognizes her. The one thing that confuses me to this day is how is it that he is the same age as he was back in 1913 then as he was when he bumps into her in the year 2008
