When returning to the Cabot House after saving Jack's sister, the player character will get this mission assigned by Jack to help prevent raiders from freeing Lorenzo. Although one can actually fail in preventing the raiders from freeing Lorenzo, the Sole Survivor still has to kill them all once Lorenzo is released.
- Upon flipping the switches and killing Lorenzo, Jack tells you Lorenzo would have killed his family as well as the player. He says his family influence was the only thing keeping his father in the asylum as opposed to Death Row due to his crimes during his life. Jack says that now that the world is "built for monsters", nothing would have stopped his father from presumably returning to criminal activity. You can choose to thank him or berate him for being sad only because he "lost [his] mortality juice"; though Jack seems to genuinely believe he could have removed the artifact and cured his father with a little more research. He awards you with about 500 caps and tells you to return to his home in about a week. He gives you a slightly different amount of caps depending on what you say following killing his father.
- When an in-game week has passed, you will receive a notification that tells you to visit Jack back at the asylum. He tells you he figured out how to access the telekinesis effect of the artifact. He gives you Lorenzo's Artifact gun.
- Choosing to save Lorenzo by pushing the switch by his door will prompt Lorenzo to leave his cell; him saying he wants to have a "long overdue" conversation with his son. He tells you "we'll have to kill him, you know. And the rest of them." He tells you his son trapped him in there in 1898; nearly 400 years before the in-game date.
- Arriving to Cabot house, Jack will ask why you freed him. The next conversation options will allow you to either help Jack further by saying you can help him, or help Lorenzo by saying he is wrong and then killing the Cabots. Whatever you choose to say, Lorenzo will appear on the balcony overlooking the family room. Wilhelmina tries to sell Jack out by saying she would never allow him to do what he did, but Lorenzo berates the family for feeding on his blood. Lorenzo then turns hostile to the Cabots (and the Sole Survivor if that option is chosen).
- After killing him, Jack will reward you 502 caps, saying he no longer needs your services. Every quote from him following quests' end either mourns his lost family or berates you for not listening to him.
- (If successful in keeping every family member alive, asking for more rewards allows you to come back in a week to receive Lorenzo's Artifact gun.)
- Otherwise, after killing the Cabot family, Lorenzo will offer a "lifetime supply" of Mysterious serum, i.e., one at a time, which cannot be sold or traded away.
- The following describes the details for Plan C in which you free Lorenzo and then kill him before he leaves the area that is outside his cell.
- You can activate up to 3 switches and still open the door of Lorenzo's cell to let him out.
- Once he is out you can speak with him to find out what he intends to do.
- Then you can engage and kill him pretty easily. Just stay out of his melee and telekinesis range and shoot him until he dies. His telekinesis doesn't do a lot of damage if your damage resistance is over 115 or so but it does stagger you and it prevents you from aiming properly for a moment. Lorenzo's gun is a low damage pipe pistol that doesn't do very much damage. Lorenzo does have a lot of health so it will take some time to kill him if you don't feel like wasting explosives or high-damage ammo on him.
- Return back to Cabot house and Jack will be upset that you set Lorenzo free, but then you can tell him that you killed Lorenzo and that you are sorry that you did so. He will give you the 500 (or so) caps.
- After a week you can return and Jack will give you Lorenzo's Artifact gun.
Regardless of your choice above, when finished on the floor with Lorenzo's cell, don't try to leave the asylum by retracing your steps unless you have a jet pack. Doing so will lead to a dead-end under the room you dropped from on the way down. Instead, use the elevator in the control room to return to Cabot's office.
- If player is high leveled then after siding with Lorenzo in asylum it may be necessary to protect him on his way back to Cabot house. Lorenzo is not marked as essential and during his trip home could be killed by high level enemies (the Forged for example). If that happens, when you come to Cabot house you will find only dialog about Lorenzo already dead available to you.
- After accepting the quest from Jack Cabot, the previously inaccessible doors in Cabot House leading to the family living quarters unlock; you can read Lorenzo's expedition journal and look at Emogene's computer.
- Upon entering the Asylum, Jack Cabot will attempt to go through a chained door before giving up and telling the player that they need to find another way around. It should be noted that if you jump, you can activate the chain through the smashed door windows and unlock it.
- You are only able to get "Lorenzo's Artifact gun" by siding with Jack. Freeing Lorenzo does not result in Jack going to do extra research, therefore only the first method results in the pistol as a final reward. Jack may also tell the player to return in a week if Lorenzo is killed in the Cabot house after setting him free.
- If you take too long to choose between freeing or killing Lorenzo, he will eventually blow the door to his cell off its hinges himself and the quest will continue as if you decided to free him.
- If you release Lorenzo and then choose to kill him, at high levels even the Mysterious Stranger cannot kill him with one shot.
- Completing this quest unlocks access to the family portraits from Cabot House in the decorations>wall>paintings section of the workbench. Currently unknown what quest stage or condition unlocks this.
- If you have a follower who doesn't like wanton violence, you can dismiss them before killing the rest of the Cabot family to gain immortality with no repercussions with followers.
- Deacon and Nick Valentine will dislike if you open the door after killing Lorenzo. This is true even after the quest is completed. You will need to dismiss them if you wish to collect the Massachusetts Surgical Journal #1 without repercussions. However, Deacon and Hancock will like if you kill Lorenzo beforehand, balancing this out.
- MacCready, Hancock and Cait dislike opening Lorenzo's door, whether it's to release Lorenzo, or after you side with Jack and kill him.
- There's an enormous amount of salvage available on this mission, so make sure as much of your inventory is free as possible. Best to have all four stars in the Strong Back perk, so you can run (fast AP recovery helps) and fast travel with all the stuff you picked up.
- If you have a follower who doesn't like unneeded deaths or violence (Curie, for example), you can choose to kill Lorenzo inside the machine, then open the door afterwards. Your follower will dislike you for killing him, then subsequently like you for opening the door.
- Alternatively if you have a follower who doesn't like unneeded violence you can open the door, then simply shoot Lorenzo. This allows you to gain affinity without losing any.
- If Lorenzo is killed, Jack Cabot can be found wandering the wasteland. He will offer to give you a 'good price' on a scientific crafting material (e.g. Fiber optics).
- Starting this quest is the only way to gain access to the rooms containing the Charisma bobblehead and issue #1 of the Massachusetts Surgical Journal. The bobblehead is located in Jack Cabot's office and the skill book is on a cupboard in Lorenzo's room.
- When storming the asylum with Jack, there is a spot in the abandoned wing where you must jump down. If Jack just stands there and won't jump, you can push him off by walking into him. Afterwards, he should continue normally.
- pc Jack Cabot can get stuck in the administration lobby if you proceed to insane asylum section before killing all the raiders. If you make it to the elevator wihout Jack, you're stuck in this part of the facility. Alternativeley, you can get out of it using jetpack or the tcl console command.
- pc Jack Cabot sometimes spawns on the other side of the unpickable door leading to Lorenzo in the basement, preventing the quest from proceeding. This happens after following Jack inside the asylum, then leaving the building with loot and teleporting away. Upon returning Jack is on the other side of the unpickable door. No way to continue or return. [verified][platforms tag needed]
- pc It can be fixed by forcing the door to open (with console command "unlock") and when Jack gets back to the player then closing the door (with console command "lock").[verified]
- A previous load my be the only other way to continue.
- pc Completing the quest in Jack's favor may incorrectly display the quest completion text in the Pip-Boy as if you helped Lorenzo. This does not seem to affect earning the artifact gun reward.[verified]
- pc ps4 xboxone When you reach Jack's office in the asylum and find Edward, the quest marker may appear on Edward but it is actually Jack you must talk to in order to continue. [verified]
- pc When you reach Jacks office and edward is just a marker, Jack will freeze kneeing at it. Open Console and enter "prid 47ec1" after that "moveto player". Edward appears besides the player and Jack starts the dialog.
- pc Items within the Cabot house respawn at least twice during the mission.[verified]
- Once you enter the asylum, there are 2 different doors right in front of the player with chains in them. If you have Cait with you, and get too close to the wall on the right side of the middle door with chains, near the broken window facing the courtyard, Cait will open the door and head into the yard. Jack, who might have gone ahead by this time, will come back into the room and will be hostile and start shooting. Attacking him until he falls down, will stop the hostility as he resets once up. [verification overdue][platforms tag needed]
- pc Sometimes the game will fail to spawn Edward and Jack will become unresponsive once reaching his office. [verified]
- pc Entering setstage MS09 750 into the console will spawn Edward, and Jack will finally respond, allowing the player to progress the quest.
- The door to the right of that, has broken panes above the door. Jumping (easier to do in power armor) while spamming the chain unlock button will eventually allow the door to open. Jack will come back once you enter and immediately run up to the ghoul and commence dialog[verification overdue][platforms tag needed]
- pc After siding with Jack and killing Lorenzo, the last step is to "Talk to Jack Cabot about the artifact." Attempting to talk to Jack, however, will not start the necessary speech check to end the quest. Jack will only offer small talk such as "Oh, it's you" therefore leaving the quest indefinitely unfinished. [verified]
- pc This can be fixed by entering the console command setstage MS09MiscJackReward 100, and provides the artifact reward.
- After siding with Lorenzo and killing the family if you get caught looting the house Lorenzo attacks you. If you kill him the quest will not finish and there will be a talk to Lorenzo marker over a blank spot in the house where you killed him.[verification overdue][platforms tag needed]
- If the quest ended by killing Lorenzo after releasing him, but with Jack, Wilhelmina and Emogene still alive, player can kill either Emogene or Wilhelmina or both inside the house. This will make Jack turns hostile, but player can choose to leave the house and come back again a few days later to talk to Jack. Jack will have mixed dialogues of where he relieves that the family members are all alive and also blames the player for his mistake of releasing Lorenzo that results the death of Emogene or Wilhelmina, but player can still receive Lorenzo's Artifact Gun after a week has passed.[verification overdue][platforms tag needed]
- ps4 Jack will somehow turn hostile if he sees the player picks lock a "Master" safe in the basement of his house, despite the safe has no red text and all items in the house have no "Steal" option.[verification overdue]
- ps4 When siding with Lorenzo Cabot, the robot guards outside of Cabot House will come inside and attack the player once the other members of the family become hostile. If they are attacked and destroyed, Lorenzo will become hostile as well. At this point, the quest cannot be completed since Lorenzo is still considered the next step even after being killed. However, if the player does not attack the robots, leaving Lorenzo, Deegan, and a potential companion to destroy them, the quest will continue as normal.[verification overdue]
- ps4 If the player runs ahead, Jack may not follow and will not spawn when taking the elevator down to Lorenzo's cell. This can be fixed by using the "wait" command for 24 hours and then taking the elevator down again; Jack should spawn with the player this time.[verification overdue]
- ps4 If the player follows Jack on foot to the asylum and makes Jack hostile en route by attacking or pickpocketing him, Jack will attack the player and continuously respawn as hostile, because Jack is essential at this state in the quest. The player can advance to the asylum and hide behind Jack, slowly tracking Jack as he walks through the asylum until Jack disappears in front of the elevator to the basement, breaking the quest.[verification overdue]
