Tim Latimer
I just wanted to say goodbye and thank you, because I’ve seen the future and now know what must be done. It’s coming, isn’t it? The biggest war ever.
Tim Latimer was a young schoolboy who 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. 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.
Many years later, the Doctor and Martha Jones saw him again as an old man as a veteran at a Remembrance Day ceremony. (DW: Human Nature / The Family of Blood)
Behind the Scenes
According to Doctor Who Confidential, Tim had telepathic abilities due to "an extra synaptic engram".
