[X] Stay silent and watch what he does.
Kiritsugu's walk takes him out of what he classifies as the business and commerce area of Fuyuki, and into the residential areas. You can tell the change when it happens. Rather than tall buildings, now there are houses and apartments, no more than 3 stories high.
He comes to what looks like an estate common in some of the West. Expanding horizontally, with wooden walls, and elegant but simple decorations. A sign of wealth in countries with little land.
It seems wasteful to you, but the methods of humans have always been strange.
However, the most obvious sign of importance of that house was the pair of black suited guards at the front gate. They peer at Kiritsugu from behind their glasses, nod, and open the gate for him. Kiritsugu nods back, and walks in, where another man checks him for weapons, and then escorts him to a room where on one wall, a large box is placed, with a black screen and some nobs on the side. Sitting on a mat in front of the box is an old man, with short white hair, dressed in a simple kimono and drinking from a pot of tea. There is a second, empty mat next to him.
Kiritsugu nods. "Raiga Fujimura."
"Kiritsugu Emiya." Raiga returns the nod. "Sit with me. The match is about to start."
One of the black suited men turns a nob on the box, and it lights up, revealing it's purpose as a scrying artifact, which Raiga appears to be using to watch a pair of large man wrestle.
Humans really are odd.
Kiritsugu sits down next to him, and they both watch the match, commenting ever so often. You can tell that Kiritsugu doesn't enjoy watching it, but he sees the banter with Raiga as a way to ingratiate himself with the old man, and as a way of confirming his identity with the man. You and he can both tell that several of Fujimura's questions and comments are ways of ascertaining Kiritsugu is really Kiritsugu, and that Raiga's men in the room have concealed weapons.
Both of you also know that this man would not have let Kiritsugu meet him if he wasn't mostly convinced he was the real deal.
So Kiritsugu answers as he should, and by the end of the match, the guards have relaxed their guard.
"So, Kiritsugu. Why exactly do you need that gun?"
Your Prince takes a sip of the tea (It's actually pretty good!), and responds. "It's a backup weapon. The Thompson I use normally was lost in the Fire, along with most of the other equipment I had on me. While the rest I have extras of in my estate..."
"I'm the only one who has a backup Thompson." Raiga finishes. "I will return the Thompson, but I want to know what it's for. I've had some of my gunsmiths look over the gun, and they've noted some odd runes and designs in the barrel and hammer. I didn't take you for a superstitious type, but it is an odd weapon for an assassin, especially with the modifications."
Kiritsugu is silent. "It has special use against those of the darker side of the world. It is meant to be simple, hardy, and powerful enough that they bring out their strongest defenses."
Raiga smiles. "I thought it would be something like that." He motions to one of the guards, who brings forward a wooden box, and hands it to Kiritsugu.
Your Prince opens the box, and sees both the gun, and a small key. "Thank you."
Raiga nods. "One last question. What happened to your wife and assistants?"
Kiritsugu stops. You feel a vast wave of guilt and self hatred wash over him, and try and play some kind of happy tune to cheer him up. "Dead."
Raiga lowers his head. "I'm sorry."
Kiritsugu simply stands and bows. "Thank you for having me."
No one stops Kiritsugu from leaving.

In the ashen ruins of the Grail Wars final battle, Kotomine sorts through the remains cocoon of brass and hair.
Despite what Gilgamesh had said, the strange thing disturbed him. It reacted somewhat to the Black Keys, and analysis with both Magecraft and the Church's own sensing rites revealed it to have spiritual similarities to both demons and the strange horrors summoned by Caster.
He frowns, and gathers the pieces of the cocoon, storing it in a black bag. Whatever was in it was not a holy thing. If he had found this before the war, he would have decided to hunt it down. But now....
Now he would wait. If the thing revealed itself, then it was a danger to the secrecy of magic, and he would be obligated to kill it. If it did not, then it was merely another monster in a world full of them.
He shouldered the bag, and began to walk. He would examine each piece in Tohsaka's workshop. It was much better supplied than his own.
He would rather not be caught unprepared.
------|------
Kiritsugu walks only a short distance, coming to a similar house to Raiga's, but obviously less expensive or expansive. He uses the key provided to him, and walks into the house.
He removes a floorboard and takes out a case of bullets that match the gun. He begins to count them, eventually coming up with twenty seven bullets. You notice that each are marked with an small image that resembles a knotted rope.
Origin Bullets. A stray thought from Kiritsugu reveals their purpose to you. One use Artifacts which damages enemies by causing their active Magic Circuits to be cut and then shoddily reattached. An incredibly dangerous and potent weapon. You're not sure how it would effect Essence Users, but you kind of don't want to.
He puts his bullets back, and then walks to one of the closets, grabbing a grey longcoat and suit from the closet, and changes into that. He finishes, and then sits on the floor, staring at the lone decoration in the room. A picture. Him, standing with a white haired beauty and a girl who looks very similar to her mother.
Irisviel and Illyasviel. His wife and daughter.
That same sadness and self hatred wells up within him.
