Still in the Dark

 is a quest in Fallout: New Vegas.

Detailed walkthrough
This quest is obtained at the Brotherhood of Steel compound at the western entrance to the Hidden Valley bunker. To gain access to the interior of the bunker, the characters needs to have a Lockpick skill of 100 (to open a Very-Hard locked door). After entering the second door, you will encounter Senior Paladin Ramos, who will confiscate your gear and lead you to, who begins the quest. Note: The Paladin Ramos will shoot at the PC if he's dressed as an NCR troop, , and removing the outfit will not cause Paladin Ramos to stop engaging the player.

If you discovered the bodies of Brotherhood Paladins anywhere (E.G. the REPCONN facility 3rd floor) the note they have will have a password on it. You can use that password with the intercom next to the door to start the quest. Also if the player has the companion Veronica, she will go to the intercom and talk to Ramos for you, thus letting you in the bunker, while keeping your gear.
