How are lieutenant Blake and scofield different

Lance Corporal Tom Blake is William Schofield's friend and also a soldier in the British army during the First World War. Blake has a brother that is in the army as well, Lieutenant Joseph Blake. In contrast with Schofield, Blake is more affable, always telling funny stories and exhibiting a pluckier, more fun-loving attitude, even in the face of grave adversity. He is tragically killed early in the film by an injured enemy soldier he was trying to help.
