"Thank you." There is presumably some space to sit?

Indeed!

The front door opens directly to a flight of double stairs. "I'm Red, by the way," the man says as he climbs those stairs, two steps at a time. To the right of the stairs is a small foyer with minimalistic deocorations.

To the left is what's presumably the living room, with sofas and a pipe organ and a chess table and a bookshelf.

And also, a person who looks identical to the one who greeted them except for how he has golden earrings and necklace is sitting on the sofa, one leg crossed over the other, reading a book.

He looks up when the three walk in and smiles warmly at them. "Welcome, welcome!" he says, scooting over to the side and closing his book. "Make yourselves at home."

Thunder plops himself next to golden earrings. "Thank you! I am Thunder, these are Fenris and Felix. So, are you twins? Clones? Twin clones?"

"Thank you so much for having us over," Felix says, taking a seat.

"...huh," he says, after a pause. "Clones," he replies. "I'm the original, name's Cor. But you... are not spellcasters. So did you..."

"Cloning machine. I used it on myself... I don't know why."

"Well, I am not complaining."

"Me and Felix are twins, Thunder is Felix's clone," Fenris clarifies. "The cloning machine was mine."

"—well, then."

Red appears behind the sofa by Cor in a flash of pink light and places both hands on Cor's shoulders. "So?"

"They're people!" Cor says excitedly.

And Caleb Vatore—looking exactly just as tall and pale and languid as in the video, if a little bit more naked—doesn't teleport, but he's sprinted through the door so fast it was almost like he did.

"Hello, I heard you wanted to chat," he says, non-sequiturially enough.

They jump a little at the two sudden appearances. "We do," Fenris tells Caleb, "And we are people, yes?" he says, in the direction of Cor and Red.

"Hi..." Felix says meekly. "We had a confusing afternoon and would like help getting less confused, if that is not imposing too much."

"Long story short, most people aren't really people, they just act sort of like... not even robots." Shrug. "Like video-game NPCs. And then it seems like sometimes some of them kind of... spontaneously wake up."

"Are you kidding?"

"It makes sense, actually. From the TV, the people there just were odd."

"That can't be true... we have family. They love us... we love them."

"Do you have... actual family or only the vague memory of having a family? It's a genuine question, so far the only examples we have of people spontaneously waking up are, uh, him," tap on Cor's head, "and you guys. And he—we—don't have any real memories of any family members."

"It's like I spontaneously appeared one day with fully formed but vague memories of having been raised and having had a family except I can't recall their names or faces and I don't have them as contacts on my phone or anything."

"Oh, I am so sorry to hear that. We, or at least I, do remember their faces and names?" He checks his phone for their contacts.

"Our parents are Easter and Nathaniel, our grandparents are Jonas and Jocasta... I don't remember our father's parents. And we had an uncle Ernest before we were born."

"...well. If you want to run an easy test, you could call one of them and... try to hold a conversation?"

"Okay, I will do that."
