Doctor Bernadette Case is a researcher on the Ellicott-Chatham Technologies Space Station. Her primary role on the station is working with Lasers, but she is also the station Physician.
When asked, she stated, "The medicine thing is more of a hobby, really.... I mean, practicing medicine is fun and all, but compared to LASERS? No contest."
Not much is known about Dr. Case's background, other than she was basically Hannelore's physician while growing up. Jeph has stated in a Tumblr Q&A dump that "she’s in her 40s, I think, she just went grey earlyish."
Doctor Case revealed some of Hannelore's tortured past to Marten and Marigold.
