"Oh--sorry, I was just sort of curious about the accents."
"I have an odd little talent for accents and I use it to make it easier to tell us apart."
"I guess that makes sense for identicals! Me'n Wilbur have to take steps to make it easier to tell us together." She gestures at their matching outfits.
"Huh. Those're—what's all that made of?"

"Oh, those little biochemical miracle factories! Nice!"
"Oh, you've heard of them?"
"They make the materials science people angry, which is always fun."
She giggles. "We got them from the biology department, the university Dad works at doesn't have a Materials Science department."
"My dad was a mundane engineer, ran a big company, I grew up around all kindsa neat shit and people tearing their hair out trying to replicate neat shit some random bug is doing that we can't."
"Personally, I like co-opting the bug. Our dad's a linguistics professor, I keep telling people how many languages I speak and then they swear at me."
