The driver's a woman who looks really alert for someone up this late. Well, guess it's part of the job, but maybe she's a night owl, or maybe she had a big cup of coffee, or something like that. Anyhow, she doesn't see Sollux, which is probably a good thing considering that she's driving a bus.
Sunny looks up too late to see the child, at least at the moment. He leans forward towards the window slightly, his eyes darting back and forth to try to find someone who might have waved. 

(I was thinking more a summary of the ride. What did you have in mind?)

Sunny worries for a second before remembering that he asked around about this and found out that it isn't exactly illegal. Still, he has so many questions.
Not that he's gonna ask, of course. He's just gonna kinda stare into the distance instead.

The picture's printing out. Pretty neat. It is a little slow, but to be honest, it's a print-out camera, dunno what else was to be expected. 

(Yeah. So the summary is: "Sunny is tired" and "good scenery, TBD tho")

"How is it?" Sunny asks, unaware of the fact that she doesn't seem to have looked at it yet.

"It might have," he agrees, otherwise just being entirely unhelpful. In his defense, what's he supposed to do about not understanding technology? Learn it?
Yeah, not gonna happen.

"Sit up," he reminds, though he's a little bit away from slouching down himself. 
"Why did you take a picture of another bus's driver?" he eventually asks. 

"Wouldn't that be this one? Our bus?" he asks, too tired to ask about her choice of words.

"Then why wouldn't the label instead be..." He pauses for a moment to remember her choice of words, "...'The first bus we met in Nazoja while being in another bus'?"

He puts a hand on his forehead and tries in vain to remember what "vibe" means again. He's currently failing.
"Alright, 'okay,'" he generically answers instead. He obviously doesn't get it.

(Of course, what's he gonna do)
(Anyway, feels like a good place to put a timeskip. You okay with that?)

The entire trip is rather uneventful, which is just the way Sunny likes it. Though, he doesn't indicate that he likes it, instead mostly just looking like he is clearly trying not to doze off. All of the scenery outside--from the homely neighborhoods they pass to the more clearly urban elements--flies right past his head.
Conveniently enough, the bus doesn't stop the whole way, so no new passengers come on board. That means no potential polite conversations and also no potential muggings, both are which are great from Sunny's perspective. So by the time the bus gives its announcement for the name of the final stop, he can more or less afford to want nothing other than going to bed.
The bus driver opens the front door and cheerfully goes to open the storage department. Sunny looks around like he didn't just ride the bus for the past half hour and staggers to his feet.

Sunny even forgets to ask her if she wants him to keep the pictures and camera for her again. He mostly just looks outside like he just realized that the two of them are, in fact, not in their house.

(Sorry for this lol @Sollux)

Sunny doesn't move, though. He stares into the distance still, looking almost wistful save for a slight furrow of his brows. His gaze is uncharacteristically blank, as if he's looking at something other than the not-very-special window  
Fortunately, he snaps out of his trance of sorts just as quickly as he started it. He reaches out towards the bars above, as if by impulse, to steady himself. Narrowing his eyes at the door (and the departing Sollux), he slightly frowns.
How did he somehow manage to forget that they were supposed to get off at the stop before?

At least the driver doesn't seem to have remembered, or if he did, he's sympathetic enough to not point it out. He's already opened the storage compartment and grins at both the siblings, though to the groggier one, it feels like he's bearing the brunt of it.
"Ready to wrap up the night?" the driver asks.

"Yes," Sunny responds generically to both the driver and Sollux. He manages a semblance of a smile as he offers a handshake again.
"Thank you for safely bringing us here."
The other takes his hand more quickly than before. "Gladly! Anytime. I hope you both'll enjoy Nazoja. It's a pretty great city," he says, and then adds with a laugh, "if I may say so myself."
Sunny's the one to end the gesture this time. He shifts the luggage around a bit before taking it once more.

"You too." He grins and then goes back into his bus.
With the most recent social interaction now finished, Sunny stares blankly at the bus, blinking a few times. Now he's not used to the relative darkness of the city, though it's much better than outside of the train station. Other than the bus, the road is currently empty. With the buildings nearby seeming to be closed, really the only source of light were the streetlights, distributed sparingly across the road from whence they came. And what's more, the wind seems to be chillier than before. 
The young man sighs. "So now I suppose we walk back..."

"Somewhere that way," Sunny answers, until he realizes that he is, in fact, not moving his arms as a gesture, instead just vaguely looking in the direction he would have indicated.
Despite his blunder, he still thinks it's nice. He likes an empty road. Not to mention, it doesn't feel as empty to him due to the big structure the stop is situated against. It feels like another station, maybe. He's not keen to investigate at the moment, but maybe there could be restaurants or something of the sort hiding in it. He notes that for later.
Most of all, Sunny likes the cold wind. It somehow makes the setting feel more familiar to him. And anyways, it's nice that there isn't a particular flavor to this breeze. A taste of someone else's food could be nice, but usually it was just smoke, dust, and even grime. He didn't much like any of those things.
He turns around. "Let's go."
