Earlier, Nick had scouted the room through the light holes and had seen that there was another exit leading into another brightly lit hallway.
Just like the first exit, this one also had a glass door.
Apparently, glass doors were normal in this building.
After scouting out the area, Nick noticed that it was impossible to kill the two of them while they were inside the room.
However, Nick had to kill them.
Since he had moved so slowly earlier, nearly five minutes had already passed since the infiltration had begun.
The guard probably knew what was going on, and if more time passed without the supervisor coming out, the guard would probably become suspicious and check things out.
Because of that, Nick had to kill them.
He needed more time.
So, he devised a plan.
