Human Error Human Error is a side quest in " Fallout 4 " . Detailed walkthrough . The Sole Survivor might hear about Covenant from settlers or a passing trader , which will put its marker on the map and a quest entry to " Investigate Covenant . " Upon approaching the gate , the Sole Survivor is greeted by Swanson . He explains that , to enter Covenant , visitors have to pass a test to filter out " undesirables . " By pressuring for information and successfully passing increasingly difficult speech checks , details about synth s and The Institute can be learned . Swanson will be adamant about administering the SAFE test ( an adapted Vault - Tec G . O . A . T . ) to make sure the Sole Survivor is not a synth . After taking a seat at the table and answering all the questions , the gate to the settlement will open up . Unlike other settlements around the Commonwealth , Covenant is surrounded by tall concrete walls sprinkled with defensive turrets , and the houses and the yard are in pristine condition . The Sole Survivor even mentions how everything looks almost pre - War . Several companions will voice suspicions that the village is hiding something , although none of them seem aware of its true nature . Speak to Honest Dan . He ' ll explain he has been hired to investigate a missing caravan and find Amelia Stockton , the missing daughter of the prominent Stockton family . He also suggests the inhabitants of Covenant might be involved in both cases . He also offers to split the reward in exchange for help in the investigation . After doing so , Dan will give the player character what he knows in the form of a note , caravan details . Passing speech checks with him may net more caps and info . Exit Covenant and head northeast along the road , then go east at the junction to find the remains of the missing caravan and recover Deezer ' s lemonade . With a Perception of 6 or higher , a blood trail on the road close to the scene can be investigated to reveal that " the blood trail leads roughly in the direction of Covenant . " Questioning the inhabitants of Covenant yields little info as they are adamant about having nothing to do with it . They are also oddly nice , almost saccharine . To find more clues , enter the house on the far end of the settlement to discover a holding cell , a bookcase with self - help material and a locked computer . Outside , at the side of one of the houses , is a bedroll left by the caravan staff , which can be investigated , but it isn ' t clear enough who it belonged to . Hack the computer when no one is looking to find out Covenant ' s real purpose . Hacking the computer when not sneaking will turn the whole town hostile . It is also possible to gather information by speaking to one of the settlers , Talia McGovern , and convincing her that Honest Dan is a synth after passing a few Charisma checks . Alternatively , enter the shop and take the piece of paper from the trash can or pass increasingly harder speech checks with Penny Fitzgerald to reveal the clues . Another alternative is to either pickpocket the key from Jacob Orden ( the most optimal way is to steal this from him while he is asleep in the guest house ) or pick the lock to the house directly left of the gate and find the piece of paper near the door . If pickpocket is too risky , between the hours of 7 a . m . and 8 a . m . the doors to the first house on the left when entering Covenant will be open ( in general , all of the buildings in Covenant can eventually be entered without the need to pick a lock , through the expedient of following the residents around until they open the doors on their daily schedule ) . On the table is a key and a paper that has Jacob ' s password . Residents may become hostile if they see stealing . One can also find the location of the compound at the office terminal . The door and the computer are both Master locks . Once learning about the existence of the compound , the Sole Survivor can either talk to Dan or go alone . When they try to exit Covenant , Jacob will be at the gate and will try to convince the Sole Survivor to drop the case , even going as far as offering a bribe . To find the compound , head to the fishing spot west of Covenant on the other side of the lake and enter the outflow pipe . If the Sole Survivor told Honest Dan about the compound , he will be waiting inside and will follow . Continue along the pipe to face armed guards and turrets . By successfully passing a speech check , the Sole Survivor is escorted deep inside the complex to meet Doctor Roslyn Chambers . Otherwise , fighting through the complex becomes necessary . On the way there clues about people being held captive and ongoing experiments / torture can be found . Once confronted by the doctor , she explains her intentions of trying to reveal hidden synths who infiltrated the populace by creating and perfecting the SAFE test , a sort of psychological test involving studying reactions of the subject to several situational questions . Improving the test involves establishing a " baseline " and then requires various forms of psychological and physical torture to incite reactions from the subject . She also explains the reason for capturing Amelia is because they believe she is a synth infiltrator . She may offer to pay the same caps reward offered by Honest Dan . At this point , the Sole Survivor has several choices : A " fourth " option is also available to the player character . If they arrive at the compound without Honest Dan and have already joined the Railroad , they can engage Amelia in conversation before freeing her or letting her be killed by the doctor and she will direct the player character to Old Man Stockton , claiming he will give a reward for freeing her . The quest will update as though the player character has freed Amelia and the quest marker will lead them to Old Man Stockton . If the player character leaves Amelia in her cell and turns in the quest to Old Man Stockton , the quest will complete , only in this case , upon return to Covenant , all inhabitants will be friendly to the player character . If the player character has passed the speech check at the compound , all inhabitants there will remain friendly as well . Although everyone is still alive , this option offers the least amount of rewards , as there is no way to obtain Covenant as a settlement .
