How to unlock: You must improve your relations with Curie, speak with her and agree to help her.
- Bring Curie to doctor Amari
- Wait for doctor Amari
- Talk to the caretaker
- Observe the transfer procedure
- Speak to Curie
Once you unlock Curie as a companion, start traveling with her and perform actions that she will approve on. After a while Curie should speak to you. You must hear her telling you that she wants to obtain a human form. Offer her help in finding a specialist that will be able to realize her plan.
Bring Curie to Doctor Amari
You must take Curie to doctor Amari which you visited during the Dangerous Minds main story quest. She can be found in the basement of the Memory Den in the Goodneighbor location. Listen to the conversation during which you will learn that the procedure is possible and that the caretaker of dead synths will help in it. Doctor Amari will tell you that she needs at least one full day to make a contact with the caretaker and prepare the procedure. If you don't want to go back to this quest later in the game, use the bed to speed up the time. Select a bed which doesn't belong to anyone else or rent a room, for example in the Rexford hotel.
Watch the transfer procedure
Once you return to doctor Amari's office, talk to the Caretaker. You don't need to complete any additional actions, only observe the procedure during which Curie's conscience will be transferred from the robot to the body of a dead synth. Talk to your "new" companion - you can agree for her to travel with your hero or dismiss her.
Quest rewards: Experience points, Curie has a new look (later in the game you can start a romance with her).
