Long Time Coming

Long Time Coming is Nick Valentine's companion quest in Fallout 4.

Detailed walkthrough
Nick Valentine is still disturbed by "Nick's" memories, and tells of an old gangster named Eddie Winter, who used to be one of the largest crime bosses in Boston. Eddie Winter had planned to live forever, and as such, invested in a radiation experiment that turned him into a ghoul. Due to this, he hid in a bunker under a sub shop he used as a hideout pre-War.

Upon accepting the quest Nick Valentine gives 1 of the 10 holotapes the Sole Survivor needs to get a code to unlock Eddie Winter's bunker. The remaining nine are in the various police stations in Boston. Having them unlocked before reaching the required affinity with Nick Valentine can save time.

List of holotapes and their locations:


 * Eddie Winter holotape 0 - BADTFL Regional Office: In the basement, on top of a filing cabinet.
 * Eddie Winter holotape 1 - Given by Nick Valentine at the beginning of the quest.
 * Eddie Winter holotape 2 - Malden Center: On the second floor of the police department, in the corner, on top of a desk next to a terminal.
 * Eddie Winter holotape 3 - Quincy Police Station: As one enters the cell and goes down the stairs, in the locker on the end.
 * Eddie Winter holotape 4 - Natick Police Department: On the first floor, in a locker, in the sunken part of the building.
 * Eddie Winter holotape 5 - Nahant Sherrif's Department: On top of a filing cabinet right in the front on the second floor.
 * Eddie Winter holotape 6 - East Boston Police Station: On the second floor, in the southeast desk.
 * Eddie Winter holotape 7 - South Boston Police Department: On the second floor, on top of a desk in the corner.
 * Eddie Winter holotape 8 - Police Precinct 8: In a cell on the far right when entering the building.
 * Eddie Winter holotape 9 - Coast Guard Pier: On the second floor on top of an Expert locked safe.

Talk to Nick and give him all holotapes. Then follow him to Andrew station. Enter the subway and follow Nick all the way to Eddie's bunker.

After unlocking the bunker, the Sole Survivor can kill Eddie, help Nick kill Eddie or let Nick kill Eddie on his own. After Eddie is killed, the Sole Survivor can loot Eddie's unique gun Eddie's Peace. Follow Nick out of the facility, then talk to him to end the quest.

Bugs

 * If one has already cleared Andrew Station before getting to that part of the quest, Nick can get stuck standing at the beginning of the instance and later, during the dialogue with Eddie, fail to say his lines to Eddie - leaving the conversation stuck with the player in dialogue with Eddie but no lines being spoken. To fix this situation; first, teleport Nick to the bunker door with then when the dialogue freezes, turn the camera until you break out of exclusive mode, go to Eddie's bed and rest an hour. Nick should then enter the room and progress the conversation as intended. If this does not work teleport Eddie where he has to be (between the beam and the wall, in front of the door) with, then teleport Nick next to him with: . Now the conversation will begin
 * Once Nick receives all the 10 holotapes, he will immediately go by himself to meet Eddie Winter in Andrew Station, no matter where or when in the game he is. At this point, the player character will have to follow him and sometimes Nick will vanish during that travel. Most likely he will be waiting inside Andrew Station if he disappears, but if he is not there, using the console command will place the player character exactly where Nick is, to find him easily and continue the trip.
 * Another workaround is to go to Andrew Station with Nick, and clear out all enemies at the location before giving him the holotapes.
 * Holotape #4 may be missing from Natick Police evidence locker, preventing quest progression and completion. It can be found in the garden at Abernathy farm.
 * Sometimes Eddie stands there and is not able to interact with the player character.
 * Nick Valentine may not say the dialogue to end the quest after Winter dies. May also occur on other platforms.
 * Holotape #6 may not be present at the police station. May also occur on other platforms.
 * The quest may fail to trigger even when the player character reaches the required affinity level and has completed the quest Dangerous Minds. To start the quest via the command console type . This will transport the player character to the Diamond City market, outside of Nick's office and enable the starting dialogue for the quest.
 * Sometimes Nick will stop moving during the final 'Follow Nick' objective, sitting down and waiting for an hour will allow completion of the quest. Another option is moving close to the exit via speakeasy and using command to teleport him to the player character.
 * If Nick does not do anything during the "Follow Nick" stage, the console command will progress it.
 * Sometimes Nick will stop moving during the final 'Follow Nick' objective, telling him to leave the player character as a companion will start him walking.
