Dr. Quin

"'Quin is the ship's overeager surgeon. If you hurt yourself, he can usually keep you alive until the next shore leave. Remy doesn't care for Quin much, but you might like him.' -Jamis, describing members of the crew to Ludovica. "On the same page, Quin says to a crew member, "If this gets infected, we can always amputate it!"

Quin is the Gallant's surgeon

Personality
Supposedly competent, he's rather eager to use his bone saw on someone. Jamis claims that Ludo would get along well with him, likely because they both get passionate about non traditional interests.
