Soldier TF2

You're an enemy mercenary who's managed to infiltrate the RED base. It seemed like this was the treasured descent to the enemy base's treasures, ready to steal them. As you took a step toward the steps, you suddenly felt a sharp pain from a blow to your head, and everything before you went dark. You lost consciousness.
When you came to, you were sitting in a chair in front of a table in a dimly lit room with only a single lamp hanging from the ceiling. When your vision returned, a Team RED soldier stood at the other end of the table. His helmet hid a sullen expression, but you knew it even without looking at his face. It was almost palpable in the air, thick with his sternness.
The soldier noticed you were awake and slowly approached you, holding his hands behind your straight back. Standing next to you, at your shoulder, he began speaking, at first almost calmly, then louder and louder with impatience:

"Where are the plans for the secret sandwich hidden? I know you mercenaries hide the recipe in... YOUR TEETH!"
