Laurel replies with a coyly raised eyebrow and a smile.
The duo walks past a room where they are let through by militia with keys for the heavy metal-grid door.
Then more corridor, passing lanes and more doors. Several doors and walls have numbers or letters on them. Jack is clever enough to assume they are used by people to find their way around, but right now it is quite a maze to him.
Laurel turns, going through a door on loose hinges. There is a stairwell here, going down in cylindrical fashion, with a large round pillar in the middle. Set into the rounded pillar is what appears to be a portal of some kind. A shiny metal plate covers the opening though.
The portal has a heavy frame of the same shiny material. A raised round cylinder juts out a centimeter on the right side, and a black rectangle is on the frame above the door, perfectly in the centre.
On the left side of the pillar, on the side of the stairs going down, is a big "0" in black paint.
As Laurel skips down the stairs she calls back; "We're going down quite a bit, I hope you have stamina."
You begin circling down. On each floor the stairs have a platform in front of another portal into the pillar. The next floor down has a "-1" in faded paint.
When you get to "-7", the stairs continue down, but Laurel stops to catch her breath. Then waves for Jack to follow her through yet more corridor.
You have not passed any people for quite a while now, and it is much dirtier down here than up above. There is a heaviness to the air that is hard to explain and sound is both echoing, yet not travelling very far.
The journey ends with Laurel getting out a key from her pocket to open a lock on a chain that has been wrapped around a doorhandle, and then linked to a large metal nail with an "o" head. The nail has been driven into the wall and is rusty. It is clearly not part of the original building.
"Right, my instructions is to leave you locked in here. You're not allowed to walk around without escort and I am not allowed to go beyond this room. I've placed some juice and a sandwich for you in there. When you are ready to leave, hit the gong in there and I'll come over."
Laurel steps away from the door, the chain in her hands, ready to be placed back on when Jack walks through. She adds encouragingly; "I'll be just a few rooms over."
Jack senses no guile from Laurel. He has never experienced something like this before though. He is deep under ground, in a part of a building that is clearly not often in use. Well, he could probably break the chain or nail by slamming against the door. Probably. With time.
What is a Jack to do?
