The Sixth Person

As I was wondering where the sixth person was, the Principal barged in the office looking worried.

"What happened…?" I asked.

"… He is gone," she said.

"Let me guess," I said, "There was a sixth person who you shot and you believed he died but now he is gone." But how did he escape, that's a question we need to know.

"That's right. There is a window almost double your height above the stairs, but it's not for opening-"

"Between the gunfight, they broke that window letting one of them escape. They already knew that they were going to die either way." Now I get it.

"Again. That's right," she said.

"But how come no one noticed this?" There were at least 6-7 people. If they are letting people escape like this then this secret organization is nothing but a cakewalk for the HYDRAs.
