Um.

… He'll stand near the door. And look outside in case it looks safer than the subway car because. Um.

Beyond the filmy barrier, the surrounding stone narrows to a single corridor, at the end of which are two tubes full of orbs moving very quickly, up through one tube and down through the other.

He thinks he's, uh, going to go outside.

But first, he tries – and fails – to ping Relay.

So he goes outside. Tentatively.

The air is hot, and incredibly dry, but does not seem harmful to breathe or stand in.

He's okay with hot environments. He walks out a bit further and – assuming there's nothing to either side of the subway car where he is now – follows the corridor.

The film causes a cold tingle to pass through his body as he walks through, but does not stop him. The corridor, made of smooth yellow and red stone after the film, leads to the two tubes he saw earlier. They are made of what looks like cloudy unbroken glass.

Is there any water around him now? Anything obvious that he can offload some liquid from or something?

Can he see where the tubes go?

There is no water nearby. The air is very dry, and the little orbs of light don't seem to contain any water at all.

The tube going up splits into two tubes that curve away from each other at the top, and go somewhere beyond the ceiling.

The tube going down seems to be a straight drop.

Is there enough space around the tube that he could follow it, either direction?

No, more glass fills the space between the tube and the edges of the holes in the floor and ceiling.

Hmph. He doesn't really want to try smashing this glass. Feels rude.

Can he go back over to the subway car and fly over it?

He can go back over to the subway car, but the subway tunnel is set into the wall, and there isn't enough room between the car and the tunnel to climb into.

When he gets back to the weird film he pokes it.

It's weird and he has no idea what it's made of. Any hints?

He can't feel any pressure or texture, just a cold tingle going entirely through the section of his finger within the film, more gently than the first time he went through.

… He is not quite at the stage of making himself bleed just so he has something to use for his power. So he walks through the film, shutting his eyes as he does so because that was creepy, and walks nearer the subway car.

Is the orb still in it?

Walking through the film produces a gentler cold tingling than it did last time.

The orb is still inside. Now it's floating slightly above one of the seats, and glowing magenta.

He has no idea what the different colors might mean, nor why the film would produce different amounts of tingles at different times, but he decides to go inspect the outside of the subway car some more.

The outside of the subway car is gray with two blue horizontal stripes. It has the large windows and the double doors he saw from the inside.

What does either end look like? Is there any obvious thing to cause it to move?

The very ends extend into the tunnel. There is no obvious source of motion, and everything below the bottom of the door is below the floor and blocked from view.

Hm.

Have any of the orbs done anything interesting or are they just continuing to move through tubes or sit passively in the subway car?

The orbs of light are all zooming through the tubes, except for the one floating passively in the subway car.

Sigh.

He's not sure this place will be at all useful and the implication of the subway car that has already transported him somewhere is that it will transport him somewhere else if he goes into it.

So he goes and sits down on one of the seats again, making sure not to touch the orb.

The orb bobs slightly in the air and hums when he enters. After a few minutes, there is a chime and the doors slide quickly shut.

The car starts moving and is quickly surrounded in darkness again.

Woo. Maybe.

He plays a game on his phone for a bit.
