Wanted to drop off a yandere Albedo thought. Since he can use his alchemy to bring his paintings to life, what if he made like a mini living doll of his darling? Then he’s always got a version to “study” no matter how remotely he’s working.
It'd definitely be tricky ground for him... considering he himself is one of many identical 'clones', he would hesitate to consider any replica of you to be 'you' (if that makes sense... each copy of you would be seen as a different entity once physically separated from your original self). But on the other hand, he would probably enjoy having an atrocious amount of sketches, paintings, and other artistic works of your likeness with him at all times. Definitely five or six sketchbooks full of you in various poses, both from reality and from his imagination. And, if he's really fighting off a yearning itch for his darling (especially if he's been cooped up in Dragonspine for a few weeks longer than expected) perhaps maybe he'll blackout and wake up to several fully life sized sculptures of you carved from a variety of materials, including stone produced by his Vision. Trust that they are uncomfortably detailed. It may just be once he gives these images of you 'life', he'd start crossing into theoretical territory that he'd like to avoid (like mommy issues, problems of his own humanity, whether or not you'll find this clone of you, if he has to kill said clone before it harms others or you, etc etc. just normal alchemy problems)
Although at the root of the problem, if he does find himself finishing up a lengthy stay in a remote area and longing for your company by the end, he'd consider the above before eventually settling on the classic 'he'll just trick you into joining him next time'. It never gets old. After all, what's better than providing the wrong information so that the both of you are trapped in a blizzard together and you're none the wiser that he's planned it for months? You, as the original, is what he'd prefer. He'd like to think you'd feel the same way about him if you ever were to cross paths with his 'brothers'. There are certain other characters who wouldn't hesitate to keep living duplicates of their darlings though (Cough... Ruan Mei.... Cough). Even if the keeping of said duplicates forced them to consider the possibility of killing said clones. Who am I kidding? Ruan Mei would totally already make clones of you and then kill them in various ways as a means to test your biological makeup, the extents of your physical body, etc etc. She's like Albedo but without the anchor to her own humanity (in the form of Klee, or otherwise normal bonds of companionship and community).
