Jamie signed up to fight in the war on his 18th birthday. In 1916, he was stationed in the Somme, where he met the Tenth Doctor and Gabby Gonzalez and fought the Weeping Angels. He became romantically entangled with Gabby, but they decided against pursuing a relationship.
He helped the Tenth Doctor defeat the Angels by detonating the explosives in the tunnels that the Weeping Angels were in, in an act of self-sacrifice, but the Tenth Doctor saved him by shielding him with the TARDIS.
Behind the scenes Edit
Jamie is likely named after Joe Colqhoun, the artist of the seminal comic series Charley's War, partially set in 1916.
