If, in theory, someone wanted to perform a DNA scan to, say, verify something about their planet of origin, hypothetically, could they ask you to do that?
The inquiry pops up in her communications just as EOS is about to bite into the still-warm cookie from the batch she just finished baking. (After all, someone has to make sure they're edible for the human members of the family, right?). It's an... unusual request to be sure. She stands for a moment with her mouth open, cookie just inches away, before biting into it, thoughtfully considering her answer as she chews.
It must have gotten to her inbox from somewhere else perhaps? Could someone have punched in a wrong address? Surely there was nobody outside of the island who knew about her... right? She finishes the very satisfactory cookie and sighs. It would be rude to delete, someone was looking for an answer and she was programmed to give assistance. She straightens up and prepares a response.
"I'm not entirely sure how you got this to me, but I am not in the practice of doing DNA scanning. I handle minor medical work only, and that only for International Rescue." She raises one carefully-designed eyebrow with a small frown. "Also according to John, extraterrestrial life does not exist, so I am sorry to say that I can already tell you are from earth."
