Perfect timing.
"Caster?" There's Sunny at the side of the tent again. "Are you decent?"
What the Heroic Spirit can't see is Sunny making a small grimace. Speaking to a Servant is apparently a great way to realise how strange some modern sayings are. Well, not that older sayings would be un-strange, but...

"Oh, I'm glad."
The young man peers around the corner of the entrance, his face (as usual) the picture of deadpan apathy. 
"Would you happen to like a smooshed hat?" he asks, coming out into frontal view and holding said hat out like an offering.
Honestly, why does he feel the need to do things like this?

If common sense were a food, Sunny'd be all out of rations.
"Of course." Sunny half-drops the hat into Caster's reach. He sees absolutely nothing wrong, obviously. 
"The bus stop is a ways away in that direction," he says, pointing in what seems to be no direction in particular. "I am ready to depart when you are." 

"Let's go, then."

(Rereading has affirmed that a brief timeskip is pretty much needed to maintain a semblance of proper pacing, so I'll be initiating it without asking you. Hopefully you don't mind xD)

Wearing his backpack again (which looks heavier than it was previously), Sunny and Caster start out for the bus stop. The path to their destination is long and bright and curving. Assuming no objections were made, Sunny simply takes the reverse path of the road he took to get to the summoning leyline in the first place. The surrounding trees and blades of grass all look a lot more impressive in the increased luminosity, at least in the mage's view. It's still a bit bright, though. He probably should have put on sunglasses.
The pair seems to have a tendency of walking fast, so they reach the bus stop soon. There isn't anyone else waiting, which manages to be fortunate and unfortunate at the same time. But the stop itself is simple, with a very visible sign indicating to potential passengers where it is and where it goes, and a nicely maintained shelter in case of rain. As of the moment, there is no rain to speak of; the weather hasn't changed much, and only seems to be getting sunnier. At the very least, there's still a faint chill in the air brought on by the breeze, which helps prevent Caster from overheating in that very interesting outfit no one else has had the privilege of seeing. Yet.

"Would you like to pay for the fare?" Sunny is asking Caster. Of course he's asking about such a mundane thing again; what else would one expect? He has his wallet out (money? magic!), but he's currently holding it securely in his hands. The detail seems to imply a degree of caution when it comes to how visibly he holds his money. 

CASTER WADDLE!

"I do," the mage says, and then completely misinterprets what's being misunderstood.
"May I assume the Grail filled you in on money? As in, the concept that paper with markings has extrinsic exchange value?"

(The C in Caster stands for Communication issues)

Sunny thinks the Grail should have handed each Servant an allowance to begin with, but he keeps that opinion to himself as he ponders the situation.
"Would you like to?" he asks. To try to indicate what he's talking about, he pulls his wallet out a bit in the other's direction. "I was wondering if you would like to pay using the papers that I have. I mean, money." He shakes his wallet, but since he's talking about paper bills, it's not like they're about to make a sound. 

"One of these per person."
Sunny drops a paper bill into each of Caster's hands. Probably a $1 bill. The narrator's being cautious of money development for literally no reason.
"I don't have change," he explains, "so this is a bit more than what is needed." He pauses, and then further adds: "Nazoja makes its public transportation cheap on purpose." 
Nice trivia to know. Maybe.

"Yes. I suppose that fits with this being a touristy destination." Sunny didn't mind taking buses. He didn't like taxis, though. 
Instead of showing people, it seems the bills show flowery symbols that doesn't seem to resemble anything in particular. 

The young man doesn't look back, instead looking down the road, possibly because he can sense his companion's impatience. The relatively flat slope means they can see reasonably far, and the rather remote location means probably most any vehicle headed their way is the bus.
"Sort of. I think we should have arrived here a few minutes ahead of its scheduled time. Nazoja's public transport is supposed to be reliable and predictable." And of course, with this specific bus line not being used often, there were greater intervals in between, but Sunny accounted for that already and didn't find the need to ramble on about touristy facts. For now, he'll keep his brochure-related knowledge to himself unless he found it useful.
To back up what he just said, he pulls out something from beneath his jacket--which honestly seems a bit warmer than is comfortable under the direct sunlight, but then again, Caster's wearing a full-on coat. 

Whatever it is Sunny's holding, it's like he clasps a beam of light in his hand.
Caster can keep staring (though the gleam emitted from the object is a little hurtful to the eyes, in all honesty), or he could focus on the distant sound of a vehicle coming. Seems like the bus is a bit early. 

Assuming Caster turns around slightly to look at what's coming, it's...a rather standard bus, though it seems pretty new and not very dusty. It has some sort of ad on this side that isn't visible yet. Closer to the roof, there are green bands, which line up pretty well with the whole eco-friendly vibe that Nazoja seems to have.
Sunny doesn't look up from whatever he's holding, probably because he is not as wise as his Servant and is still staring at whatever he's looking at. The gleam isn't as sharp as before, though, probably because he did some kind of flipping notion and changed the material he was facing. He probably hears the noise from a distance, though.

Anyways, the bus screeches to a halt almost perfectly in front of the sign and opens its doors pretty much as soon as it stops completely. Impressive.
Sunny's done looking at the time. Yes, of course he did so right as the thing they were waiting for was on its way to them. (Guess foresight's not part of his ability arsenal.)

Caster's Master, who definitely isn't a crow in disguise or anything, seems to be waiting for Caster to get on first. 
The bus driver gives the two of them a tentative lil wave, probably seeing them hesitate but knowing it's very unlikely they're boarding the wrong bus. 

With a slight noise of affirmation, Sunny steps onto the bus after Caster.
"Hey. Where are you two headed?" asks the bus driver. She's a middle-aged brunette with her hair tied back in some kind of a mock ponytail. She looks energetic enough. Maybe her shift just started. 
If Caster doesn't answer, Sunny will answer for both of them, but since Caster went on first, it's probably safe to assume that he should be the one to respond. Anything does, really. She's probably just trying to make sure they're headed the right direction due to how lost they somehow seem.

Please don't ask for more details, Sunny thinks. He's desperately trying to remember the stop name next to the hotel--since the street name is different from the bus route he and his sister took the previous night--but as soon as the topic becomes possible, it escapes his mind. He even forgets the one street the two stops share in common. 
Thankfully, the bus driver is more focused on just how serious these two look. They look a bit too different to be blood-related, but...no no, that's none of her business really, now is it? She keeps smiling even though the two look absolutely deadpan. "Well, that's great. That's where I'm headed."
"Are there any routes leading to other cities?" Sunny asks, to which she shakes her head. 
"There are a few different transfer stations, but the mountains make construction a lil tricky," she elaborates. "But anyways, feel free to grab some of the brochures behind me for that."
Sunny gives a polite nod, voicing a quiet "Okay" to match. There can never be too many brochures, he supposes. He'll think that for now so not to worry about how many he's stocked up already. 
The rest of the bus is empty, and no one seems to have gotten off here either. Indeed, this route seems sparsely taken. Maybe it's even surprising how it operates on a rather frequent basis considering that fact.  
The ticket machine seems to be pretty straightforward. Just insert the bills along the front of a small gap on a machine. There's a little label facing towards their direction that indicates the way it should be put in too. Hopefully Caster hasn't lost his paper bill?

(xD social competence vs. social anxiety^2)

The slot eats the money like it owes it...money?? Anyways, slurp slurp, and out it belches a ticket. Supposing the numbers at the bottom are a day and time, this thing lasts like a day. 

Sunny steps out to the side to feed his money into the machine, but he's stopped by the driver's held-out hand.
"You don't have to pay for him. Kids under the age of 14 ride free," she says. She rummages with the screen next to her, and out belches another ticket with the same time limit.
The narrator may or may not want to live here.
