Tim Latimer

Tim Latimer was a schoolboy who attended in Farringham School for Boys in 1913. His history master was John Smith.

Biography
The fob watch containing the Doctor's Time Lord essence communicated with him and instructed him. It could do this because Latimer had low level telepathic abilities it could access. It 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 have his watch to look after and for good luck. He fought in World War I 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, a veteran at a Remembrance Day ceremony. By this point he was apparently wheelchair-bound. He still recognised them and silently acknowledged them, with tears in his eyes. (TV: Human Nature / The Family of Blood)
