"Exotic matter from the world of a sci-fi game called Mass Effect, does variable funky things to mass depending on which way you run current through it."

What about Quirk-made eezo?

That depends on the fidelity of the reproduction. If it is accurate enough not to need ongoing support from the Quirk that made it, and instead depend solely on eezo-variant physics, then it only spreads that variant, not Quirks.

How do we tell?

Your Companion's Quirk can't produce Quirk-dependent materials, so her reproductions are exactly as accurate as they appear. Other methods of reproducing exotic materials may vary. 

Good to know, thanks.

"So that answers that, I guess?"

"I suppose so."

"...It is not theoretically impossible that I could undergo a Quirk awakening that would allow me to produce Quirk-backed materials."

...If you are concerned about spreading an exceptional physics that is possibly *deleterious*, we have developed a monitoring system that *tracks* exceptional physics, which can operate utilizing the Company-provided device's more esoteric hardware in a manner its developers probably did not intend. Ensuring that you do not permanently introduce something is not something we can solve for you, but if you are reasonably diligent and cautious, this should ensure that you won't *accidentally* spread something unless you are deprived of an opportunity to remove it.

Yes please!

"Ooh, that'd be great! We can check!"

Once again, a momentary glitchiness is followed by the appearance of an app.

"It does seem like this will be useful."

"Yeah!"

She taps open the app, and it reports the presence of one individual utilizing Quirk-variant metaphysics, as well as one individual utilizing "comic metahuman"-variant physics, in a pocket universe actively supporting both of those. No variant-dependent objects are detected.

"Well, we know it works.  Maybe try shooting some webs?"

She smiles and nods, shooting a web at the tree. The scanner app updates to list one comic-physics-dependent object, noting the distance and that it's temporary.

"That's really convenient."

"I wonder what the Opposition usually uses it for."

"Maybe some kinda stealth stuff?"

"Probably."

The sun's rather further below the Skyblock than she thought it was, Momo notices, as a yawn suddenly overtakes her.

Yawns are contagious, and Ruby finds herself doing the same.

"Maybe we should wash up, eat supper, and wind down."

"That sounds like a good plan."

Though, to be honest, she's suddenly contemplating that she will become very bored of Only Persines in, say, a month, when faced with thinking about the prospect.  "If we end up somewhere modern we should try to get cuttings to propagate.  And seeds.  The persines taste good but not good enough to live on alone forever, you know?  ...Should probably try to stock up on high-calorie supplements for my Quirk, too.  And for your metabolism."

She nods eagerly. "Yeah! Seeds and meal bars and dried food and maybe a bunch of eggs or something to keep in the cooler."

"Maybe," she concurs, a sudden upwelling of fondness causing her to lose the rest of her train of thought to the pernicious forces of Gay™.

Where was she -- oh, right, washing up before they eat.

She'll wash her hands and pick out some persines and cut them, setting the seeds aside and the slices on plates, giving Momo one and a third fruits, and herself two thirds. She thinks that's about right, given that it wasn't that heavy of a web-production day, and Momo's been making a whole bunch of stuff, and they each had a whole persine for breakfast. That brings them to two banked persines currently. 

She stares off at the twilight sky as she waits for Momo to be done showering.

And Momo, after quickly showering, will join her.

"Thank you, Ruby."

"Mhm! Glad to."

She picks up a slice of persine and raises it in a mock toast. "Cheers!"
