Doctor Sun

Doctor Sun is a doctor and facial reconstruction surgeon who resides in Diamond City in the year 2287.

Before the completion of The Disappearing Act, Doctor Sun can be found in the Diamond City market.

Background
Sun is a very accomplished doctor who provides medical treatment such as purging radiation, restoring health, and addiction rehabilitation. He has been working as a doctor with Doc Crocker for a decade, but doesn't consider him a very competent doctor. Sun also sells medical supplies and can provide facial reconstruction surgery in place of Doc Crocker for 100 caps, but considers it to not be real medicine.

Effects of the player's actions
After completing The Disappearing Act, he can be found inside the Mega surgery center. The entrance is between where he used to be and Solomon's Chem-I-Care.

Other interactions

 * Doctor Sun has no more talk options other than asking him what are the treatments available, however, if the player character has Curie as a companion, she has a chance of approaching him and inquire which university he graduated from, Doctor Sun then replies with a laugh and asking if she is serious.
 * He can be used to save Danny Sullivan during the quest In Sheep's Clothing.

Appearances
Sun appears only in Fallout 4.

Bugs

 * Sometimes after completing The Disappearing Act his dialogue choices do not change, making facial reconstruction surgery impossible.
 * After completing The Disappearing Act and meeting Doctor Sun in the cellar, it's possible to request facial reconstruction surgery but not be able to sit in the surgery chair. He does not receive payment for the first conversation. Talking to him again and paying him will make the chair usable.
