"Wow! Clones are not normally the same person if you do not do anything about it. And you do not look like clones."

"Clones are members of the birthday-set for the day they were born on!  If someone were to clone me, but that clone were born or decanted on a day that wasn't the winter solstice, he wouldn't be any more like me than anyone else is."

"Hello I'm back."  The other one jogs into the room.  "Your genetic code is extremely weird!"

"I think the genes for this are actually pretty close to typical in my universe."

"Wow!  I wasn't able to tell much about your specifics because you seem to be made out of only double helixes."

"- Wow!"  Bounce bounce bounce bounce.  "Here all creatures have quadruple helixes for their genetic codes."

"Huh. I am not aware of any species in my universe which uses quadruple helixes."

"Stots.  That's kind of concerning for whether you'll be able to safely eat our food..."

"Oh dear."

"Yeah."

"This just ate - quite a fair bit - of our food."

"...Oh dear.  Hm."

"Probably there's no birthstone that would help but - we're not that far from the emergency room, if we go at the first sign of something wrong that should have as good a chance as anything else of helping -"

"I seem fine so far. I could induce vomiting, but this will in fact just die if not fed so I'm not sure there's a point."

"How confident are you that you could tell if something started to go wrong with this body?"

"I do normally have to do all my own maintenance."

"Good.  If you start to feel bad, let one of us know right away, and unless somebody comes up with a better idea we will take you to the emergency room.  Much of our society's crystal healing relies on tailoring the treatment to the subject's specific birthday and/or condition, but not all of it does, so there's a chance one of the more generic arrays will still help.  It seems likely to me that even though you know how to take care of your ancillaries with resources from your world, crystal healing is the current best bet because we don't know what else might be different about the resources you would use."

"I do not think crystals in their capacity as crystals are common in any medical equipment in my universe."

"That's very good to know.  It's still my best idea for a fallback that might work while we research other things that might have a better chance of working, so I still hope that you'll tell us and go to the emergency room with us if you start to feel bad."

"Okay."

"Now that we have a baseline plan established, what would you normally want to try if you were in a situation with similar resources but more confidence that they would work the way you normally expect?  If you thought there was a risk this'd been mundanely poisoned, away from the rest of you."

"Well, I'd want to make sure I could find me, so that if this died I wouldn't lose any memories."

"How would you go about that?"

"Ideally I would send myself a distress signal or contact the Presger. I do not think I can do either thing from another universe though."

"I agree that you can probably not do those.  Do you have a next best option in mind?"
