Bestyakh apparently sensed the presence of something sister along the way. She had disembarked from the Mist Train ahead of everyone else and was on guard around the area.
While we wanted to get there as soon as possible, the situation was that something comparable to the White Wind may lie ahead, according to Yakutsk.
Yakutsk	"It's no good if we become secondary distressed units here. It would be bad enough if we had to retreat after an unsuccessful rescue, but it would be worse if we couldn't move the Train."
Yakutsk	"This may just be speculation, but there's definitely something unpleasant going on in the direction Bestyakh is talking about."
Queensway	"I think I can trust Miss Bestyakh. Just like Miss Tayshet, Miss Bestyakh has a lot of practical experience in cold environments, so she should be our reference."
Putra	"If something as bad as the White Wind is here, we should avoid it. We're not in the best of shape either."
Vivienne	"Hey, Bestyakh, if your expectations are correct, do you think we can accomplish the mission with this crew and equipment?"
Bestyakh	"I can't say for sure because I don't know what it is that I sensed... but I think we should retreat as soon as we can see it."
Vivienne	"It's very unsettling. Even at this stage, I think we're on the edge."
Yakutsk	"It's got the magical power of a White Wind, that's what it is. I'd like to coordinate with the Metro's Railway Army and plan a bit more before we head out."
Conductor	I'd like to hear more details again about the presence of the object that Bestyakh sensed. Even if this is just a guess, I'd like to know if there's anything we should be aware of.
Bestyakh	"As I told my sister earlier, I felt a bad presence, like a mixture of magic and cold air. I have a feeling that it's something that can freeze creatures in an instant."
Bestyakh	"Some types of anomalies will occur before detecting any signs of monsters. It could be a sudden drop or rise in temperature, localised snowfall, or strong winds."
Bestyakh	"The usual way of looking at this is to see it as a Phantom Mist, except this is no ordinary Phantom Mist. It is a Phantom Mist with special properties, like a White Wind. A vortex of magical power and cold air over a wide area. And it's moving quite fast too."
Queensway	"How can you detect such a thing when there are no traces of it? Even Miss Yakutsk didn't notice anything at all."
Yakutsk	"Bestyakh is very good at reading the weather and the flow of magic in cold climates. This girl trained as a warrior alone in the northern tundra after deserting the Eisengrad Army."
Bestyakh	"That's part of it, but I also learnt how to fight inside the Mist from the executives of the Resistance. They had the ability to deal with any and all unexpected eventualities."
Vivienne	"I have this image of the Resistance leadership as a group of overpowered freaks."
Yakutsk	"I don't want to talk about the Resistance anymore. The situation then and now is completely different."
Yakutsk	Bestyakh is the SSS Train Knight. I want you to be aware of that and to be ready for the mission."
Bestyakh	"Agreed. Dear sister is right."
Vivienne	"So? What are we going to do? Do we change our route? Or do you want to check things out first?"
Yakutsk	"We don't have time to investigate here. We will rescue Tayshet and the others as planned. But I think we should change our route."
Yakutsk	"The way to the observation point is not that far. Changing the route won't affect the arrival time too much. I think we should proceed with caution here. Don't you agree? Conductor."
Conductor	I have the same opinion. If what Bestyakh felt is related to this incident, there is no doubt that it could be a major blow to us latecomers. Let's slow down the pace of our march and bypass the planned route.
Conductor	That object is a mixture of magical power and cold air. Regardless if it is a Phantom Mist or some other bizarre phenomenon, if we can avoid it, we should do so.
Yakutsk	"It's decided. Let's change our route. Let's go around from the west."
Yakutsk	"Bestyakh. Stay alert."
Bestyakh	"..."
Yakutsk	"Bestyakh?"
Bestyakh	"I, just saw something."
Yakutsk	"What did you see?"
Bestyakh	"I don't know. But for a split second I thought I saw something glow in the dark."
Vivienne	"Could that be Tayshet's distress signal?"
Bestyakh	"No, Tayshet would think of another way. If she were to use light, she would have sent a clear signal."
Queensway	"Did you have meetings like that with Miss Tayshet?"
Yakutsk	"Those of us who know the polar regions of Eisengrad know the fear of glowing objects in the danger zones. Because if you use light in a call for help, 'they' will be alerted."
Queensway	"Fear of shiny things in danger zones..."
Queensway	"No way, a Silver Lantern!?"
Bestyakh	"We haven't heard the name yet in the Metro universe, but it wouldn't be surprising if there were similar flowers in the same Eisengrad."
Putra	"But what if it's Tayshet? It could be that she fell down, got stuck and the light reflected off her belongings."
Yakutsk	"In daylight, sure. But it's now Nacht in Metro. These celestial spheres have been silent for a long time. There's nothing to reflect the light."
Bestyakh	"Avoid the anomaly, or dare to approach it. It's a difficult choice."
Bestyakh	"Luckily, from where I saw the light, I don't feel that nasty presence. It could be that we are still safe, so why don't we take a course that way?"
Bestyakh	"...Of course, I leave the final decision to dear sister and Conductor."
Yakutsk	"I think it's fine. Let's go the way Bestyakh says."
Bestyakh	"Dear sister..."
Yakutsk	"Have more confidence. You were selected for this."
Bestyakh	"...Yes!"
