After Leonel finished making their acquaintance, the guy simply left the room and let them interact by themselves. Casper even tried to stop him or to follow, but he just brushed him off and said for him to get along with his teachers.
The soldier just kept sinking in despair as long as he saw that door opening and closing again and the second most sane person of that place left and went anywhere else.
"Get along? That's easy to say, but what about if they start to attack me again out of nowhere. They won't kill me, but, man, my left arm still hurts, what the hell does the blade of that knife was made of!? Also, now I am the only most sane person in this room, I must be careful, otherwise, those guys will drive me crazy for sure…" Casper was getting a bit uncomfortable to be alone with those three because of the possibility of they do something idiot again.
