Sawbones (Fallout 3)

Sawbones is a Mr. Gutsy working as a doctor in The Citadel. He can be found in the B-Ring and offers the same services that all the other wasteland doctors offer.

When you first interact with him, you can ask to be healed, in which he malfunctions and ends up hurting your player character. After the mishap, a new dialogue option opens up and (if your PC has a high enough Science skill) you can repair his malfunction through dialogue choices to receive some free healing. He will also comment to the player about fixing the malfunction, calling them an 'asshole', giving the assumption that he's not interested in healing, but harming.

His terminal, which requires 100 Science to hack, contains a poem of his composition. It also appears that Paladin Glade has hacked his terminal before, and wants Sawbones to change his password.

If you've finished Finding the Garden of Eden but haven't spoken to Elder Lyons, Sawbones will not treat you, or even converse with you, but will prompt you to seek him out to start the next quest.

Note
After repairing Sawbones malfunction and receiving medical treatment, an effect called "Sawbones Percision" will appear in your pipboy, giving you +2 END and +2 PER. The duration of this effect and wheter it can be gained agin is yet to be confirmed.

Trivia
Sawbones' behavior is based on the E.M.H. Mk I holographic doctor from the Star Trek Voyager TV series. They both open with the same "Please state the nature of the medical emergency" phrase and both have an interest in artistic expression as well as a certain lack of empathy towards patients (as evidenced by the medical report citing patient discomfort as irrelevant). "Sawbones" is a historical slang term for a surgeon, dating back to the early 19th century.
