While the others move around, and mingle, you stay in place. You're decently sure Lavenza wasn't being entirely literal, but that's not the same as being completely certain, and you don't think you want to take the risk right now. She's sort of one of the only people you can rely on.
You can see, with just a glance around the room, that some of the others are also choosing more sedate activities than conversation. Chidori-san, for example, has her sketchbook out, and appears to be trying her hardest to get the image of the Velvet Room accurately laid-out on the page. You wouldn't really be surprised at all if she ended up stealing colored pencils from the art room later, or something. She'll probably be at it for a while.
Morgana, meanwhile, has curled up in the middle of the room. He seems incredibly comfortable here, which is weird, given what happened the first time you tried to introduce him to Lavenza. Despite obviously trying to get a bit of a catnap in, he has yet to return to his housecat form.
If it's like last time he was in a place like this, it might just be that he can't turn back. I can't imagine sleeping in that form would be comfortable...
Makoto-san is taking notes. Or possibly making adjustments to the map. You aren't sure how he'd be able to do the second one without actually being in the Labyrinth, but he seems to be giving it his best shot.
Still... you suppose there's worse places to do it. Whatever may be said about the people who live here, the room itself is nice and peaceful.
Maybe you can just... enjoy that peace, for a little while.
When Lavenza comes back to the room, she is closely followed by Elizabeth. "I... see you've all been making yourselves comfortable," She says, her voice and expression as unreadable as if she'd been taking lessons from Makoto-san. "With my sister here, we may be able to discover the cause of this... anomaly."
"By 'anomaly', you mean the boon, correct?" Elizabeth asks, sounding more confident in her words than Akira has been in his whole life. This is saying a lot less than it should, but it's still something.
Aigis blinks at her. "What part of Makoto-san being unable to change his Persona would you call a boon?"
"It would be best to start from the beginning," Lavenza decides. "This anomaly in the powers of the Fool Arcana is occurring due to the presence of multiple Wild Cards within a finite world."
"A finite world..." Zen repeats, his voice quiet. "Yes, that is... what this place is. A finite existence. One that will, in all ways, come to an end."
Even in memory... Once we're done here, it'll be gone from even that.
Zen's words make you feel... sad, almost, though you can't see anything to be sad about at the moment.
"I guess that explains why we can't leave the school," Mitsuru-san says.
Lavenza nods along. "Exactly. This is a margin world- one that exists between the layers of reality more deeply than even the Velvet Room..." She glances at her surroundings. "...Most of the time, at least. You cannot explore a world beyond the school because it simply does not exist. And in a finite space like this... the infinite potential of the Wild Card is morphed into... something else, which has never been seen before."
"Huh?" Junpei-san seems confused. "How does that work?"
It's Elizabeth who answers him. "Imagine, if you will, a box. This box has a set of preset dimensions which may not be crossed. Now, to this box, add an infinite supply of liquid of some kind. Soap, perhaps. Or water, or blood, or whatever you prefer, so long as it is fairly fluid."
You think she may be drifting from the point she was trying to get at. Just a little.
Rei has her face screwed up, and she's clearly trying to think up the scenario that Elizabeth presents. "Um... uh... ...My head hurts."
"Maybe don't try to comprehend infinity," Lavenza sighs. "It's... not something meant for the human mind, particularly when the scenario my sister presents doesn't even need infinity to to be explained- just a larger finity than that of at least one dimension of the box. When that dimension is filled to capacity, the liquid will turn back, and start to overlap with itself, part of the liquid- or power, in the case of the changes to the Wild Card- will return to its source."
This almost makes sense, except that there's clearly something missing from the explanation you've been given. Or several things, but there's one that stands out to you the most right now.
[ ] ...If that's the case, shouldn't Makoto-san and Elizabeth just be more powerful?
[ ] ...So, what does the presence of multiple Wild Cards have to do with this?
[ ] And this is stopping Makoto-san from using his other Personas how?
