Doctor Dala

Doctor Dala was a pre-War scientist operating in the Think Tank in the Big MT

Background
Doctor Dala was the first head chief researcher of mineralogy who became a think tank to continue her work at the Big MT, such as studying Saturnite. When the Courier meets her, she is the head researcher on humanology and lobotomites, and has 211 doctorates from mineralogy and humanology to medicine and holotape eidetics.

Dala has an arguably unhealthy fascination with the human body. It would seem she has pent-up sexual frustrations (though she would never admit such as accusation to her Think Tank peers) and she can only find release in examining living tissue or observing various physiological actions. Other members of the Think Tank refer to Dala's collection of formography — explained as obsession with the human body — as if it were a hoard of fetish material.

Shortly after the war, all of the think tanks, along with Dala, went insane. Doctor Mobius replaced her and her colleagues' pre-War memories and names with that of their new eccentric counterparts, trapping them forever. This explains her extreme obsession with the human body and supposed 211 doctorates in sciences which do not exist. Mobius then fled to the Forbidden Zone where he likewise went insane.

Quests

 * Welcome to the Big Empty: The player has to talk to Dala as with the rest of the think tanks to complete the quest.
 * Picking Your Brains: After completing Welcome to the Big Empty, the player needs to talk to Dala and the rest of the think tanks to complete this quest.
 * Coming Out of Her Shell: Dala would like to monitor your "biorhythms" and observe you as an organism.
 * He Came... And Went: Dala can start this quest by picking the right speech choices in conversation.
 * Old World Blues: If Klein can't be convinced otherwise, Dala, along with 2 other members of the Think Tank, are needed to convince Klein to give up trying to escape the Big MT.

Effects of player's actions
As long as the player completes "Coming Out of Her Shell" before confronting the Think Tank at the end of Old World Blues, she will side with the Courier if the option to have Klein consult with his colleagues is taken.

Other interactions

 * Speech options can imply that she shows more emotion than the other doctors, especially if the Courier has the Lady Killer or Cherchez La Femme perk.
 * After completing Coming Out of Her Shell, you can return to Dala once a day for a "breather" (literally letting her watch you breathe) for some ammunition (depleted energy cells) in return.
 * If the Courier has an actual teddy bear in their inventory, a new dialogue will be available.

Appearances
Dala appears only in the Fallout: New Vegas add-on Old World Blues.

Behind the scenes

 * You have the option of telling her "The Quick Scribe jumped over the Lazy Paladin" which is a line Christine says in Dead Money. This is a reference to a pangram, but not a true pangram itself because it is missing several letters of the English alphabet.
 * Dala's statement regarding no standing on the green pipes is a reference to the movie Airplane! and the announcements in the terminal about the white zone and red zone.

Bugs
It is possible that you won't be able to initiate another "Breathing Session" with Dala after you have already done so once before.
