Yvette's Sunday is comparatively boring. It's still busy, of course, but in a very straightforward kind of way. She has a list of things to do, and gets to doing them. First is the plasma fruit - it's retrieved from her mailbox, and she plants and waters it. Then it's maintenance for the rest of her garden, followed by very carefully and systematically grafting plants together. Some of this is directed - she has a pretty good idea of how to eventually graft plants together in order to get a life fruit - and some of it is just. Systematically experimental. Having lots of produce and flowers to pull science materials from is only going to be to her benefit, and if she just so happens to make and fill out a tidy little spreadsheet that contains all gardening answers in the world, well, good! That will bring her joy.
Next is playing the gacha seed packet game again; she has the suspicion that the onset of Summer will mean different plants, and she turns out to be correct about that. Apples, basil, bell peppers, cherries, and elderberries all get added to her side yard, which is... very rapidly running out of space. Uh. She'll plan to maybe move somewhere else, with a bigger yard. Or possibly something with a greenhouse - her green peas have mysteriously stopped giving off produce in a way that tells her they are now out of season. She suspects that's only going to get more annoying as time goes on. So she'll have to go house hunting at some point, probably.
Then, feeling very weird and terrible and wrong, she. Gets a bag of trash from the trashcan on the curb, dumps out all of the contents into a great big pile behind her house, and resolutely tells herself she will not look at it again until at least tomorrow. Yes, this will make sense later. Probably. If Oberon was right about how to acquire seeds for the rare trash fruit, anyway. She doesn't see why he wouldn't be, and she's very glad she asked questions to this effect, because she would not have figured this out on her own. But. This does physically pain her, even if it is in service to growing immortalizing fruit.
The rest of her Sunday is spent foraging in Innisgreen, because she does still want to become a fairy, much as becoming a vampire seems pretty tolerable.
By the end of her evening, she has successfully acquired a fairy seedling, though not actually from foraging. She literally just started walking up to fairies and asking if they had a fairy seedling, and if she could pretty please have one. This worked on the third try, with some lady called Titania. The strange purple-pink seedling gets buried in her front yard, watered, strange glowing veins and all, and Yvette feels extremely accomplished when she finally heads to bed.
