Sherlock had not left his son's side for weeks. He had not eaten in days. It was ripping him apart. John could see past the wall he had built years ago to hide his feelings and keep people out, but Sherlock did not notice what John had felt. It had hit John just as hard, but he was determined to strong for both of them. Many of his friends had died in the army. Back then he had built his own wall. He did the same thing now, but this was different. This was his son. He could not put up his act much longer.
