A Loose End

A Loose End is a Brotherhood of Steel side quest .
==Quick walkthrough==
==Detailed walkthrough==
If Virgil still lives, the quest begins when the Sole Survivor speaks with Lancer Captain Kells either during Liberty Reprimed after convincing Madison Li to work on Liberty Prime (or after speaking with Professor Scara) or after that quest has been completed, and after the side quest Duty or Dishonor has also been completed. Kells orders the player character to kill the super mutant Virgil. The Sole Survivor then must find and talk to Virgil. They will then have the choice to either kill Virgil or spare him and lie to Captain Kells. Alternatively, Kells can be convinced with a Charisma check that Virgil has been cured and is no longer a threat; this option may be taken while receiving the quest or after going to meet with Virgil. After picking either option, the Sole Survivor must report back to Captain Kells, who will reward them with the Visionary's T-60c helmet.
==Quest stages==
==Notes==
* Liberty Reprimed does not need to be completed to start this quest; only finishing the 'Speak to Doctor Li' objective is necessary. 
* It is possible to bypass the Charisma check by choosing the "not a threat" dialogue option, which causes the Sole Survivor to lie to Kells that they have already taken care of Virgil. Kells will congratulate them for being one step ahead and yields the same rewards.
* If the Sole Survivor built the signal interceptor for The Molecular Level with the help of the Minutemen or the Railroad and then continued the Brotherhood of Steel questline, they can still receive this quest even though the Brotherhood would technically have no idea of Virgil's existence.
* If there is still an active quest for Kells, such as Leading by Example, it must be completed for him to assign this quest.
** If the quest Tactical Thinking has been started, the player character will be unable to speak to Kells about this quest without progressing the other one, which will cause the Railroad to become permanently hostile. If looking to preserve ties with the Railroad, this quest must be completed prior to completing Blind Betrayal.
* It is possible to obtain this quest even after the player character has been made a sentinel. Kells even has some unique dialogue.
* If one decides to go with the Brotherhood of Steel quest-line and blows up the Institute without obtaining the serum for Virgil, he will become angry and immediately start attacking the Sole Survivor after a short dialogue.
*This quest can still be given if Virgil has been transformed back into a human in Virgil's Cure. There will be a Charisma check to convince Kells that Virgil is no longer a super mutant, potentially ending the quest without having to confront Virgil.
