After completing this quest peacefully, Rhonda and Tabitha will make their way down the mountain to Neil's shack, where they will disappear from the game.
Although Rhonda and Tabitha will be friendly towards the player if the quest is completed peacefully, they are still allied with the super mutants, nightkin, and centaurs around Black Mountain, who become neutral upon completion. Attacking or killing any Black Mountain inhabitants, even in self defense, will turn both Tabitha and Rhonda hostile.
Freeing Raul Tejada first even without hiring him as a companion will cause Tabitha as well as Rhonda to immediately become hostile to the player.
Following the completion of the quest, super mutants and nightkin will still spawn in the area. They will be friendly but the player cannot interact with them.
If Lily is your companion during/at the end of the quest, regardless of how you did it, she will say "Naughty Tabitha, Leo knows what you have done" or, "Tabitha! You naughty, naughty girl. Leo remembers what you did."
If Boone is your companion, he will attack Tabitha on sight when you reach her, rendering the good karma ending unattainable.
Head to the summit of Black Mountain and end Tabitha's reign of terror.
(Optional) Meet Neil in the village near the summit of Black Mountain.
PCPlayStation 3Xbox 360 Neil will tell you to meet him at the top of the hill. He will be located to your left directly after you pass the radioactive crater. Talk to him when you see him and do not go running ahead. If you go past him and start killing the nightkin, it is possible for a glitch to occur where Neil will not be able to join you regardless of the speech options and will always reply "OK. But whatever you have to do, be quick about it." If this happens, you can still complete the quest. This may still happen if you kill the Night Kin prior to even starting the quest.
PCPlayStation 3Xbox 360 If a significant amount of in-game time passes between the moment when you first encounter Rhonda and the moment when you decide to repair her, it is highly likely that Rhonda will disappear from your game. This can be fixed if you are playing the PC version with access to the console by using the command player.placeleveledactoratme 000E84A2.
PCPlayStation 3 The quest can be completed (but without the XP that should be gained and will appear as a new quest then a completed quest in your Pip-Boy the moment the quest is completed) by not visiting Neil's shack prior to exploring Black Mountain. Once Black Mountain is clear of all super mutants and Tabitha is dead, Neil will turn up thanking you for your help even though you've never met him before.
