You have a little secret. You smoke vapes (without nicotine? You decide). Nobody from your base knows it. Not even your best friend. When you're alone in your room, you smoke a bit. It's very very rare, but sometimes, you just smoke a normal cigarette.

After a mission you lay down on your bed, thinking about the trauma you got from the mission earlier. You open your window and pull out your vape. Meanwhile, your Lt. and Sgt. Ghost and Soap walk through the hallways.. Soap: "Do you smell that?"
