It was quite funny that the Spartans used to have around 30 Johns, but even though Nick had not even killed half of them, he had most likely gotten all or most of the team leaders.
Nick looked around the office for a bit and gathered a couple of documents that seemed important.
"Alright," Nick said to the Grey Room. "Let me check how the outside looks. I'll be back soon."
Then, Nick turned into smoke and entered the light layer again.
About half a minute later, he returned.
"I know what we're going to do," he said. "First, we need to clear the hallway. One of the Extractors is currently walking to one of the offices here. You can take care of him."
Nick grabbed the glove on the right hand of the dead team leader and put it over his right arm, stuffing the old glove into the pockets of the corpse.
Then, Nick opened the door with the glove.
