Emergent Behavior

Emergent Behavior is one of the companion quests in Fallout 4.

Detailed walkthrough
After gaining 250 affinity points with Curie, she asks the Sole Survivor if they have a moment to speak. She claims that her robotic nature and lack of "Human Inspiration" prevents her from progressing any further in her research, and asks the player character to help her become more human.

If the quest Dangerous Minds has been completed, the player character can then suggest asking Doctor Amari, memory specialist at the Memory Den, to help.

After dialog with Doctor Amari it seems that this kind of transfer could work if using a synth body. Doctor Amari tells the player character that she has performed risky memory-wiping procedures on willing synths desperate to escape the Institute, and that some of those whose procedures have failed are now in a persistent vegetative state as a result and Curie can use one of these synths.

After waiting a day for the caretaker of said synth to bring her to the Memory Den, the player character can then initiate the process in the basement of the Memory Den, and Curie becomes a Generation 3 synth, experiencing human feelings.

Behind the scenes

 * The title is possibly a reference to the philosophical stance of Emergentism, which is the belief that consciousness can be an unexpected 'side-effect' of, or that it 'emerges from', complex interactions in a system, like a brain or a similar computational system. In any case, Curie behaves like a conscious entity, which makes her qualified for consciousness under the philosophical doctrine of Behaviourism. The title 'Emergent Behavior' catches both these aspects.

Bugs

 * If Doctor Amari is killed in any way, the objective may stay on "Bring Curie to Doctor Amari" and not fail, making it impossible to complete the quest. This effectively eliminates the chances to get not only synth Curie, but her companion affinity perk as well.
 * Sometimes upon successfully transferring her to her new body she will have a glitched smoking animation while idle with no weapon equipped. No work-around has been identified yet.
 * This may be fixed by reloading an old save and traveling to the Railroad. Glory will then be the caretaker of Curie's synth, and Curie will not be smoking.
 * If the Miss Nanny version of Curie has been flagged as protected somehow, the script will fail to kill the Miss Nanny. If you speak to it, it will speak lines from the stage of the quest where Curie waits with Doctor Amari.
 * Sometimes, when the scene begins for Curie to be transferred to her new body, the old Curie (Miss Nanny) is not present, but the voice is heard. After completing the transferal, the old Curie body can be found upstairs in the main room of the Memory Den.
 * Upon completion of the quest one can get two instances of experience being awarded.
