He'll feel the 'tug' of low mana before he reaches the end of the list.

He writes down how many card-imitations it took to do that and what is clearly marked as guesses to how draining each thing was.

"Sadde, you want to try to imitate the rest of the cards? It occurred to me it might be a bad idea to be critically low on mana just from experimenting."

"Yeah."

He does so and reaches the end of the list before reaching the end of his mana.

"So we have a solid base of possibilities. Brainstorming time? Thought of something about loop - if you make a loop and cross the line and cancel it almost immediately it would work kinda like teleporting, wouldn't it?"

"Ooh, I think so! I wonder how to even direct it, though. Like, do you have to just tell it where to loop or?"

"I'm going to test that. Loop!" Tap. "Please loop the area I am picturing in my mind." Just this one room, but the point is to see if it can do it without him saying.

It apparently cannot

For completeness, "Please loop the space within this room."

Well that one works.

And it is bizarre. There is a moment of vertigo, looking like the world is tilting sideways and twisting, and now the room is—infinite. In all directions.

"Urk. Loop, cancel, dispel, something-"

It stops.

"Well that was something. I'll test it properly in the park, later."

Sadde's looking a bit dizzy. "That was kinda weird. There were lots of other usses."

"Yeah I-" He blushes, inexplicably.

"—where did your mind go to, I wanna go there."

"Um, are you sure you want to know?"

"Of course I am."

The Blushening 3: Blushing intensifies.

"W-well, have you heard of. Something called sixty nine."

"As in, the sex position?"

"Yyyyyes."

"Mmhm?"

"Well, I, uh, imagined something similar using Loop's help." The blush is not receding, "It'd still be really disorienting though..."

Kero: is nowhere to be seen.

"—oh. Like, on yourself?"

"Nnnn, actually well that too, but mostly sixty nine where we wouldn't, uh, be looking at each other's feet. Not that this means I think that is a brilliant idea we have to do now or anything I mean..."
