You and Onney are busy taking apart some old projects for scrap.
A knock on the door, then the clinician you spoke to earlier and the weird Sym walk in.

The Sym sits in a chair, while the clinician stands in the doorway, "did I show up at a bad time? Sorry about that, and sorry for being late, she was hungry, so we picked up some lunch on the way."
You eye the clinician's wet hair and the Sym's outfit. They must've stopped at the spa's hot tub, too.
"Just take it easy with her please, she was on death's door just last night and I don't want to hear it if you end up killing her."

Onney seems a bit miffed, "Syms don't die and they don't get hungry either, idiot." The clinician just stares at Onney, not sure how to reply to the weird animal lady with the huge thighs.
You point out to Onney that they CAN die or get hungry, if they're programmed to.
"Well what kind of idiot would waste time with that? Why would someone program a Sym to starve? You might as well program them with STDs or make them hiccup!"

The clinician seems nervous and is clearly eager to leave, so you thank them profusely and let them go, promising not to let anything happen to the Sym.
You and Onney decide not to report the Sym to the Sym research team quite yet, as you two are pretty curious about why she's such a big deal and want to get a good look now, just in case the SRT takes her from you.
As far as either of you can tell, she's a pretty standard EndoSym like Dettna, and your scans confirm that, but unlike Dettna's simple insides, this Sym appears to be made very poorly, like she was made in a hurry by someone who doesn't have the right parts or tools to do it properly.
You blame Onney for the second time this week, as she's pretty well known for hodgepodging things she's not supposed to, but she convincingly denies any involvement.

The whole time, the Sym is just sitting there, rubbing her stomach, listening to the two of you chatting. A gurgle, then a long belch, "ahh, tummy good. Good food!", speaking to nobody in particular.
Onney glares at the Sym, then at you, looking quite giddy, "did you hear how good that audio sounds? Oh, can I take out her voice box, please? Just a quick look?"
The Sym covers her throat, looking up at Onney with more than a little worry, "nuh-uh, insides inside!" She scoots to the furthest edge of her seat away from Onney.
Very interesting, she has the voice of an adult woman and could pass as such with your eyes closed, but her speech seems broken and her vocabulary seems limited. If it wasn't for how badly her insides were put together, you'd assume she was some special project's conclusion. Maybe she was a cutting-edge prototype that wandered off? Maybe she's damaged in some way?

Why is she using an existing Sym design, anyway? Seems like a waste to make a whole new Sym and just copy an old design.
You have her enter the holoroom, then spawn the standard design next to her. Onney adjusts a setting when you're not looking and there's suddenly a pang of jealousy in the standard one, eyeing her twin's hefty breasts.
Further scans show the mystery Sym is only bigger and fatter than the original because of all the excess parts inside, most of which are either in the wrong spots, or are too big or too small for her design.
Leaning over, you grab her belly a bit (she looks away and blushes hard) and give it a slight shake, it feels like shaking a thin silk sack of tools, rattling and clanging inside, though you can feel she had a big lunch. You get the feeling that this is what it feels like when she's "emaciated", and you're a little curious what happens if she gains a bit of weight.

You and Onney decide to hang onto her for a day, not telling the Sym research team about her until you've had a better look.
