Look at the face of this young man. This is the face of reality hitting him across the face in the middle of war. A bleakness, a new emotion he has never felt before, a feeling of wanting to go home but realizing he won't be the same. The knowledge and experiences he has experienced have made a deep impact in him mentally, the thousand yard stare. Knowing that those acquaintances he met during training are gone, knowing that the ones that are still there run the same risk of leaving, knowing he is in the same place as this occurs, questioning why he went to war in the first place, asking if he'll even live after the war, and if it will be worth it. All of these questions running through his mind subconsciously.
