The fragment of wrapper is pink with a stripe of yellow, has a spiky edge, and was torn off as a triangle along a dotted line.

The borders of the book of mazes seem to feature a tall many-legged figure and a small fluffy thing being reunited across various cartoon mountains and rivers.

Whoever filled out the first few pages of mazes did a lot of backtracking and smearing the chalk. The backs of some of them have blocky drawings of what might be another being like the many-legged one in the mazes.

Many-legged beings. Such an interesting repeating design. Sigh.

If he looks out the windows to the subway car can he see anything or is it just dark, like a tunnel? Presumably there are also lights inside the car.

Outside the windows, it is completely dark. The car is well-lit by three long strips of unflickering fluorescent lights in the ceiling.

Still no water around?

Can he get into another car from this one?

Still no water around. There are doors at the front and back of the car, but they don't open, and their windows show only more darkness.

… He will look at the pamphlet again, in that case, see if he can get any information out of the probably-garbled text and see if anything else is relevant to why the heck this subway car just abducted him after appearing in the middle of nowhere.

According to the pamphlet, subways are a great way to reduce traffic and transit times, and are less stressful than driving.

The map shows a series of curved lines in different routes, all passing through one point. Each line has several dots, probably stations, labeled with different strings of characters. Some of the routes split into branches, or go beyond the edge of the pamphlet.

The times listed are labeled with the same character strings as some of the dots, but the time table seems to be cut off as well.

If nothing suddenly interesting has happened around him, to his surroundings, he will go look out the side of the subway car and try to get a view of something. Despite the fact it seems completely dark. Maybe there's something below them and he can get an angle on it.

He can see a bit of the side of the subway car with the light from the window, but nothing else.

Sigh. Does he have cell service?

Nope. Nor GPS signal, but his battery's doing fine.

This thing hasn't screwed his battery over, wonderful.

… Presumably no WiFi either?

No WiFi either.

Sigh.

He thinks he will sit on one of the seats, in that case. Wait for something to happen. He would've expected a response from Relay if he were still able to contact him, but there hasn't been anything, so he's probably quite cut off from where he was.

Especially since he's pretty sure Relay can reach planet-wide. At minimum.

The seat is decently comfortable.

There certainly is a lot of darkness to move through.

He will keep looking around and keep alert, ready to jump away if anything dangerous happens.

… And after a few minutes he will get a bit frustrated by the boring, stupid darkness, and a few minutes later he decides that he is going to try punching something to fix the situation.

Is there a window that is labeled 'Emergency Exit', by any chance? Maybe with a hammer nearby, though the hammer is optional.

The windows are completely lacking in labels and hammers. And light.

He will punch one, then. He can punch quite hard. Not quite superhumanly so, but definitely at the top end of human, and he knows how to throw a punch, even at a stupid, freaking window.

The glass fails to break, with a dull thud. It hurts his hand to punch, but not as much as punching something that hard should have.

Oh, how nice of the window.

He tries harder.

This produces a thud as loud as the previous one, and about the same impact to his arm.

It doesn't cause him to, like, damage his hand any more, feel like he might have broken a bone, that sort of thing?

No. His hand feels like he punched the glass hard, but not very hard, twice in a row, and does not feel very damaged.

… If he punches it even harder?

Same result: Medium-loud thud, sore but uninjured hand, uninjured window.
