Dangerous Minds

Dangerous Minds is both a quest and achievement/trophy in Fallout 4.

Synopsis
With Kellogg's secrets at hand, The Railroad have plans to use them to help further their goals into infiltrating the Institute and rescuing as many synths as possible.

Walkthrough
This quest can be acquired from more than one source, with slight differences in the early stages. The Sole Survivor will need the cybernetic brain augmenter, looted from Kellogg during the course of completing an earlier quest, Reunions.

If acquired from Nick Valentine Speaking to Valentine in Diamond City after the events of Reunions, Nick will suggest paying a visit to a neuroscientist, Doctor Amari.

If acquired from Desdemona Desdemona will reveal that Doctor Amari, a scientist under the employment of Memory Den within Goodneighbor, is working for The Railroad, and has the equipment and means to decipher Kellogg's memories. However, in order to access her services, the Sole Survivor must agree to Desdemona's terms, in which she demands the enhancements under her personal possession afterwards. Agree with her terms, or deal with her under less conventional means.

Continuation, regardless of quest giver
 * 1) At the Memory Den in Goodneighbor, Valentine and Amari will be awaiting the Sole Survivor's arrival with the cybernetic brain augmenter.
 * 2) Amari will then use Valentine, being a synth, as a conduit for the Sole Survivor to use to travel across each of the still intact memory nodes. After putting both into the memory loungers, they will both be put to sleep, and the experiment will begin.
 * 3) The Sole Survivor will then need to travel across each of the memory nodes in sequence (the path is linear). Interaction with a memory will reveal more and more of Kellogg's past, and how he ended up finally becoming involved with the Institute.
 * 4) At the final intact memory node, it is discovered that the Institute uses teleportation technology within its courser models of synth, which must be retrieved to gain access to the Institute.
 * 5) Valentine will offer advice on how to survive radiation exposure in the Glowing Sea.
