"That seems hard to test. We can activate a card, have it go somewhere else, but that means using it, which isn't the same as an uncaptured card."

"Hard to test if it can lead places?"

"The question isn't about places generally, it's about the locations of cards. That seems like a thornier problem." 

"I just mean we can try to get the Maze to lead to my kitchen so that in the worst case it'll lead us to 'the top of the clock tower' rather than 'where the Time is.' We already have a means of figuring out where Cards are in general, and if the problem is 'uncaptured Cards block the Maze's presence in their vicinity' then all the other experiments are also moot so might as well run this one."

"Maze card, take me to Sadde's kitchen, release!"

Once again everyone else is hidden from each other and the kitchen from Scott, but there is a clear path.

He follows the path.

Kitchen!

He rejoins the others. 

"Anything else to try?"

"Whether Cards can affect you inside the Maze."

"Try the Change on me while I'm in there?"

"Yeah." She glows and—

—is now holding the Change.

"Maze, take me outside Sadde's door, release!"

Maze takes him there, hiding Sadde and everyone else from view.

Nothing else seems to happen.

Well, he gives it an extra minute or two just in case, but after that, he dispels it.

"Apparently I can't affect you from the outside."

She uses the Card again—

—and there, much more comfortable.

"That's a good sign. Okay. Uh, what else? Or is the plan kind of ready?"

"The Time is supposed to be very powerful. We should try the Windy; it's gentle, but it's one of the most powerful cards."

"Yeah, that's probably a good idea, but what should Windy do? She's a very physical Card."

"And I suppose if she can't get past the walls, that doesn't necessarily prove anything? Kero, what's our most powerful card besides Windy?"

"The Maze, and then the Storm."

"Right. So I'll try to use the Storm, and the Windy, and we'll see if either of them can affect you."

Nod.

"Maze, hide me from their magic, release!"
