The Inspiration of Rassilon

Username: justice_turtle
Era (if any): Three, Four, Eight, Ten, Eleven
Characters/Pairings (if any): Liz Shaw, Harry Sullivan, Grace Holloway, Martha Jones, Rory Pond-Williams
Plot Bunny Summary: The Five Actual Doctors (Well, Four Doctors And A Lizard Nurse). Which is to say: I just now found out, from this excellent but mildly heartbreaking tribute vid for Caroline John, that Liz Shaw had a degree in medicine. And promptly went "omg YOU were the first actual-doctor companion? I never knew!" So I rounded up all the medically-trained people who have worked with the Doctor (that I could remember; additions heartily welcomed!) and, um... can't actually think of anything to do with them. Therefore, TO STRAYBUNNIES! *flails nobly* XD
Any Other Notes: Um, I think that sums it up?
