Set during Inception, in the scenes where Ariadne is working on the dream layouts and when he's showing her the ropes. Also, I don't know anything about architecture, so just role with me on this please.
"Dammit!" I yelled.
It was well past midnight and I was still working in the warehouse. I accidentally calculated each building a little longer than I imagined and now I couldn't fit a bridge in the sketch.
As I started to erase, someone spoke. "What's wrong with it?"
I looked up to see Arthur standing in the shadows. "What are you doing here?"
"I was finishing up some paperwork when I saw the light on. I've been standing here for about and hour now." His face was expressionless, like standing around and watching people talk to herself while working was a normal daily activity.
"Well, I used to much space for each building and now I can't add the bridge." I told him.
"Well, you could either forget the bridge, or you could cut out some of the buildings in the sketch."
"You really think I should cut out the buildings to add the bridge?" I asked.
"It's worth a shot." He winked at me and then he was gone.
