Slice didn't have to go to the meeting room. 
Slice was already in the meeting room. 
Slice had been hard at work in the meeting room for four hours. 

He slid one of the chairs noisily across the floor into the far corners of the room, standing back and appraising it like a fine antiques dealer looking for the flaws in what he knows is a forgery. He reached into his pocket and pulled out a palm sized red book, flipping it open and studying what was on a specific page for a few moments, then he reached out cautiously and nudged the chair slightly off kilter with the tip of his boot. He stuck out his arm in front of the chair, nodded sagely, moved to another spot and did the same, nodded again, and hastily scrawled some notes in his little red book. 

All the chairs were in similar situations as this, scattered around the room like guests at an awkward party. Hardly any of them were facing one another, a few were facing directly at the wall, a few had potted plants sitting in them that he bought yesterday. Some of them had pieces of paper taped to them bearing the names of his squad mates. It was a jumbled mess but, according to the principles of "Feng shui" as he understood them, the room now had the optimal flow of luck. He tore a little page out of his book, wrote "Andrew" on it, and pinned it to the chair he had just been fiddling with. 

Not a moment too soon, as he suddenly received the message to head to the meeting room. He rubbed his hands together in anticipation and sat backwards on the chair he'd marked for himself, resting his chin on the back of it. This would be good. Every single chair that was meant to be sat in was at a fulcrum of good luck. In addition, every plant sat at a fulcrum of bad luck. That way no one would be sitting in them, and he'd know he'd done it right if any of those plants died. 

It was better than testing in on people, even people he disliked. He already had enough ghosts after, him he didn't need more. Hopefully what he'd done here would mean that this mission wouldn't go as tits up as the last one.
