"...have you been here long enough to know if these made-up cohabitors actually, uh, work, in the being able to leave your body awake at all times sense?"

"Not yet, especially over the long term, but I do know that the only thing that has yet stopped me from reading an engaging book is physical fatigue kicking in.  And if that fails, well, we may as well use our spare time to get in shape.  Given the monsters, and our preferring not dying."

"...get in shape?"

"...Exercise; pardon her misuse of idiom.  We lived a rather sedentary lifestyle, and now is the best time to build new habits.  ...Though there are some things we ought to talk to a doctor about, in the medium-term, so perhaps the direct meaning isn't wrong."

"Well. I hope you're right about your cohabitors working well enough. What do you need a doctor for?"

"Some private stuff that can be solved, instead of merely continually - if successfully - mitigated by my homeworld's medical science, by troporting at it hard enough."

"...okay. I can't recommend you a doctor if I don't know what kind of troportation you need, people specialize."

"...Huh, howso?"

"Everyone can drowse mice and do colors but only a few people can do, say, souls, or things that involve a lot of transfers from animals, or what have you."

"...damn, now I'm idly wondering if I can get a tail; I know my breed of human actually has the reflexes to use it still.  Just human-to-human body-feature troportation, though."

"You can get a tail. They're not very popular. Uh, do you have... someone you want the features troported from? That's not the doctor's job."

"Not yet.  I have only just gotten here, remember?  Though I could probably find someone, with luck.  Though I'll probably have less chances because cohabitation exists, and that's gotta include cosmetic alterations to taste, but still.  People sometimes change their minds about their desired forms."

"...I'm hoping that most of that unpopularity is the expectation of chair-related problems, honestly, because - they're useful.  Open doors with your hands full, shut doors behind you without having to spin around, just carry something extra, help yourself balance, there's room for accessories...Are there bad side effects or something?  If you can just casually smooth over whatever when you have the - because normally just cut-and-pasting a tail wouldn't work, but if it actually integrates..."

"...Curb your enthusiasm, me, there's probably a reason I haven't seen anyone photosynthesizing, yet.  ...Damn if I'm not tempted, though."

"I don't actually know why tails are unpopular but I don't... think I'm aware of any animals that can open doors with theirs."

"...Well, yes, most wouldn't have the intellect nor scale necessary.  But a human-scale tail, on a human, would do it.  On the third, mutant hand, I should probably ask a xenografting specialist these questions; you're a chemist!  We were talking about chemistry at some point...Honestly, I don't know all that much about chemistry where it's not related to other fields I take interest in, other than that chemical fertilizers exist.  ...Oh, and gunpowder.  Sulfur, saltpetre - huh, that's a fertilizer, KNO₃ - charcoal.  Goes bang when you set it on fire.  ...Most chemical fertilizers can explode, if I recall correctly.  It's probably the nitrogens.  ...I wonder if you can troport meaningfully increased crop yields, over time, by feeding your crop plants weeds' capacities to absorb nutrients and convert them into growth...And the selective breeding capabilities!  ...If they're heritable, at least.  I'm probably retreading old ground, anyway, I expect y'all have somebody who thought to use the most important tool on the most important resource, before."

"Troported traits are heritable among people, at least, my kids have my eyes and the color was moved to this body rather than being here already."

She is so excited by this information!

"That's a) awesome and b) holy shit I can't imagine how it's doing that and I want to find out!"

"You're awfully excitable."

"Imagine that today, you opened your eyes for the first time, and found yourself in a beautiful art gallery.  That's me, but with troportation.  Wouldn't you be excited, if you found something wonderful, powerful, new?"

"I'm not really an art person but I suppose I don't know what it'd be like if I'd somehow kept my eyes closed all my life."

"...Yeah, it's pretty hard to imagine fundamental deprivation, I suppose.  But - isn't troportation really cool?"

"It's... fine? It's very useful."

"Yeah, I suppose the shine will end up wearing off eventually, but right now?  It's very shiny.  It's - magic, y'know?"

"...yes, it is?"

"I have only ever been able to imagine magic.  And now I can do magic."

"I'm glad you're enjoying it. Uh, do you have anything else about chemistry you wanted to tell me?"
