You guys captured Purity?
It turns out the answer is "only slightly less detailed than needed to memorize the topography of a person's skin," if that's a coherent and generalizable concept.
Original-Ashras says, "...Well. Are you sure we couldn't all fit on the bed on your floor? How sure?"
"That was incredibly hot," boy-copy opines.
"Very," girl-copy agrees.
"I'm somewhat sure? I'm not completely sure. And it occurs to me that we're in the middle of the ocean so as long as I don't fall asleep I could actually probably conjure a larger room here..."
"...It occurs to me that we're in the middle of the ocean and if you get to the point of wanting to fall asleep you will nevertheless have to fly us all the way back to shore and then go home. Maybe we should take our chances with the size of your floor."
"Fair enough, I suppose." The two copies disappear. "We got distracted, though. Was there more you wanted to test?"
"...Yes but it can wait and I really want to explore the possibilities of duplicate makeouts right now."
"Awww, but I wouldn't want to keep you from your science." She lands and takes a few steps to close the small gap to him, sliding a finger along his chest. "I'd feel so bad if I distracted you."
"And yet, here you are, distracting me." He kisses her. There may be growling.
Oooh, growling! That's very exciting. She wraps her arms around him, but pulls away. "Dear me, am I. What a terrible person I am."
"You're delightful," kiss, "and delicious," kiss, "and beautiful," kiss, "and I adore you."
"Hmmm, I think I am wicked. Look at me, keeping you from productive, prosocial work, just with my aura. Gosh, who knows what I could do if I actually tried! I must have a silver tongue."
"I am making a perfectly reasonable and well-considered decision to go make out with you and leave the rest of this series of tests for later."
"But how can you be sure I'm not subtly influencing you into doing something you'd prefer not to?" she says, and doesn't wait for his answer before she starts nibbling on his neck.
"I know because, mm, I very much prefer making out with you over not doing that," he says.
"I could still be messing with your preferences," she says, her hands wandering while she continues to nibble on him.
"You aren't, though."
"Hmm, then I think I should try harder."
She hugs him and kisses him and lifts him because flying kisses are the best and also she doesn't strictly need to see where she's going, at least while they're still above the ocean.
Hugs! Kisses! Flying!
The kisses have to stop for a while because Sadde would prefer people not know she can fly.
She eyes her living room/bedroom speculatively. "We won't fit on the floor, but I could conjure something like an extension to the bed and that'd probably be enough."
"Sounds good to me."
Pop, pop, pop! Copies! On the bed!
