"I might be able to keep track of you if we do things slowly – magic sensing – but it's not immediate, so yeah, could be an issue."

"—I said holding," she says, and fumbles to try to find his hand.

Eventually she will find it! "… Do you think this is gonna be an issue when we walk through the wall? Or do you think it'll just make us somehow solid and also not."

"This magic seems utterly ridiculous."

"I mean worst-case we fail to go through or something?"

"… Why would you–?"

"They're holding hands so they can find each other."

"– Oh. Well, no, worst case I'd say would at least be you get bits of the skin on your hand unable to go through and getting ripped off while you try."

"Well, we can try it very slowly."

"Probably a good idea."

"Let's go?"

"Yeah! We could use the Fly for that, too."

"For – getting into the building?"

"For getting to the right floor."

"And then just casually walk through the wall after being lifted by it and – okay I think I should just start taking that this'll work on faith and then work out a backup plan if it doesn't."

Fly?

Fly!

"I mean, why would you expect it to fail?"

"Because I could fall through the wall if it's too thick and I don't walk forwards enough? Because I don't understand how it selectively lets me go through things anyway? Because this whole thing is bizarre?"

"Yes, sure, but we just spent several days performing tests, you should be used to the bizarreness by now," she says, poking him on the side. "And one of the parts of bizarreness is that the spell can run out whenever, so go."

Onto the pink winged stick! Up they go!

Up up and away! The card is in that one room.

That-one-room-wards he goes!

Then: attempt to step through the wall, with Sadde.

The attempt is successful!

There's a five year old writing on his notebook.

… Does the five year old seem inclined to stop that anytime soon?

Not particularly.
