"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."
