After arriving a Huerta Memorial hospital, I have a choice. I can bring my old friend Dr. Chakwas aboard the Normandy, or I can ask her to enjoy her retirement for once and bring aboard Dr. Chloe Michel to serve as my ships doctor instead.
Aside from the chance at a token Paragon/Renegade doctor while trying to recruit Dr. Michel, is there any long term difference that comes from bringing one or the other of the two doctors aboard?
Or are the physicians functionally interchangable?
