Canon talk is awesome. Carry on.I could see a quarian maybe-somehow getting exposed to eezo if they were mining for the right company. Not sure how it'd get through the suit, though. And I always assumed it had to directly contact them/didn't radiate through anything.

The way humans get Biotics (I believe its the same for all non-Asari species) is for a child to be exposed to Ezo while still in the womb and then be lucky enough to not die horrifically from Ezo poisoning. Quarian immune systems being what they are, I cant see anything less than a 100% death rate for in-utero children exposed to Ezo....
I'd say there was probably a rare occurence of Quarian Biotics before the Geth happened, back when their immune systems still worked like they were supposed to, but now It hink they'd just die.
