PARASITE open thread!

Yes; I assume that when a a patient spontaneously recovers from a coma, but lacks any memory (either of their life experiences or operational memory of things like 'speech' and 'walking'), one would do a MRI to assess brain damage. Since Sal makes a point of telling us exactly how much testing she's had done, and Symbogen knew what was in their worms (unlike the doctors in the ER) and that they were directly crediting them with Sal's survival, I can't imagine they'd overlook this.

Heck, it could explain why they were so interested in keeping Sal on-campus as much as possible, as well as why they paid for her medical care: both to study her more and to keep other interested parties (like the government) from finding out what was up. I suspect only the fact neither Sal nor her parents trusted them (and her parents were well-connected enough to raise a giant stink) preserved Sal's freedom as long as it did.
