In this quest you will use the Cybernetic Brain Augmenter to dig into the memories of Kellogg. If you did not bring it with you, return to Fort Hagen to retrieve it. You can take either Nick or Piper with you on this quest. Nick is a key part of the quest so no matter which companion you have with you, Nick will be waiting at The Memory Den in Goodneighbor.
Fast travel to Park Street Station then head east from there. Be careful as there are a few Super Mutant strongholds in the area as well as several Feral Ghouls, some Raiders and even some dogs. Fortunately, if you don't want to deal with enemies it's not far from the station to Goodneighbor so you can sprint the whole way if needed.
If this is your first time entering Goodneighbor, when you enter you'll be greeted by a Ghoul who will try to extort from you, only for the Mayor to enact some discipline on him...
Head through the alley in front of you and you'll come out right in front of the Memory Den. When you enter, Nick will have a casual flirt with the owner, Irma. She'll gesture you to go downstairs to the basement, where you'll find Doctor Amari. Talk to her and offer the Cybernetic Brain Augmenter, which she determines will work within Nick's brain. When it initially doesn't work, she'll suggest that two minds could crack the Institute encryption and gesture you to sit in one of the memory pods.
The next sequence is a linear progression of Kellogg's memories. In each scene, interact with Kellogg for some back story, then the other characters in each scene to find out more. The memories will each play out and fade, at which point Amari will instruct you to move to the next one. Once you've completed all of the memories, you'll awaken with new instructions, to find Dr Virgil in The Glowing Sea. This will trigger the next quest The Glowing Sea.
Before you leave the basement, make sure to check all of the tables, cupboards and desks. There are loads of items for grabs including Stimpaks, RadAway and Rad-X in large numbers.
If you brought a companion other than Nick with you, when you head upstairs you'll be asked who you want to take with you.
