While Silas was in his dream world he could hear a loud noise, probably coming from reality, not that he bothered. It was probably the old man getting mad at someone again. However shortly afterwards he felt a presence near him, the old man was now standing in front of him. When he got back to reality he only heard him say "Why do you wanna join the military?"

Silas was silent for a few seconds, looking at the old man as if he was crazy. "I want to see what is beyond these walls, and explore it." he said passionate. "A dream that only can be accomplished if all of the Titans have been killed... yes... that is why I want to join." he didn't even look the old man directly in his eyes but stared off in the distance of the skies, as if he could see himself exploring beyond the walls without any Titan that would attack him.
