Dr. Borville

Dr. Borville is the only Doctor in Hyrule Castle Town. He refuses to treat Prince Ralis, despite treating Ilia. He owes Telma a lot of Rupees. It is said he charges large amounts of rupees for his services and doesn't like treating other races (as shown when he didn't properly treat Prince Ralis). He doesn't like to talk to people unless they have a large amount of Rupees with them.

Dr. Borville also helps in bringing Ilia's memory back. By giving him the Invoice, he will tell Link the location of the Wooden Statue. Also in his house/hospital, Link will find the Medicine Scent, which is crucial to getting Ilia's memory back.

Trivia

 * The old scientist inside the Lakeside Laboratory in Ocarina of Time and the Marine Research Laboratory in Majora's Mask resembles Borville, possibly making him a descendant. However, Borville seems to hate Zoras, unlike the scientist, who helped and lived near Zoras in both of the aforementioned games.
