For Fallout 4 on the PlayStation 4, a GameFAQs message board topic titled 'Having trouble with Virgil on glowing sea'. A Loose End is a Brotherhood of Steel side quest in Fallout 4. If Virgil still lives, the quest begins when the Sole Survivor speaks with Lancer Captain Kells during Liberty Reprimed after convincing Madison Li to work on Liberty Prime (or alternatively, speaking with Professor Scara), or after the side quest Duty or Dishonor is completed. He informs them that the super mutant Virgil must be. Evil Route - you can con Virgil into killing himself, with 3 speech checks - he doesn't have the guts for it, but if you do it for him after convincing him, you can take his. I entered Virgil's cave wearing my T-45 power armour with Codsworth as my companion. Otherwise all 4 occupants will be hostile to you. Fallout 3's ending.
