Crazy, Crazy, Crazy

Crazy, Crazy, Crazy is a side quest in Fallout: New Vegas.

Detailed walkthrough
As you near Neil's shack or approach Black Mountain from Hidden Valley, a super mutant named Neil approaches you and automatically starts a dialogue. He will tell you that a super mutant named Tabitha has taken over Black Mountain. One of her rules is that no humans are welcome to the area and any that approach should be shot on sight. This will automatically start the quest, which requires you to enter Tabitha's stronghold and put an end to her chaos.

To get you started, he will also let you know that the area is patrolled by super mutants during the day, while at night, a cloaked nightkin patrol the roads. With a Speech check of 50, you can convince Neil to assist you in killing Tabitha. From Neil's shack you will have to make your way up the road towards Black Mountain. There is a long way where you will fight against three patrols and checkpoints of super mutants or nightkin. If you choose to take the normal path up the road, the 3rd Patrol of super mutants will include one nightkin. There are also two short cuts:
 * Short cut #1 (NE): On your way up you will find the body of an NCR trooper. If you pay close attention you will see a bear trap exactly at the legs of the corpse and all the way up to that hill. Be careful to avoid bear traps and falling rocks if you choose to take this path. You get a warning about rock falls about half way up the path, on a sign. A little beyond that point a trap is triggered and a giant Indiana Jones type boulder rolls down the path, which you can avoid by backing down the path until it flares out to the right or left and hugging the rocks to the side.
 * Short cut #2 (SE): This is the same as the short cut from Hidden Valley for the Still in the Dark quest. At the northeast end of the switchback path up the mountain, you'll see a rocky path going west. Follow that path to the irradiated crater with centaurs and the dead paladin patrol from the Brotherhood of Steel. Kill or sneak past them and climb the ridge to the south. This leads to the locked (75 Lockpick) gate into the Black Mountain compound, bypassing the Neil and nightkin encounter in the "village". If you don't have (75 Lockpick), you can go to the left, there you will see a door on the other side of the fence, as you point your cursor at the door you get the option to enter the door, you will now be inside the compound. This is also where you find the terminal) which tells you about the hidden key. Be aware that a deathclaw may be waiting at the top of the summit (it has also been seen walking up the winding road to the summit of the mountain). Once you reach the summit you have 3 options:
 * Talk to Neil and he will help you by misleading the guards at the entrance of the main buildings. This requires you and your companions to move past the guards by stealth since you choose to avoid fighting with them. When Neil returns from giving false information about "an intruder in the entrance of the Black Mountain" he will start walking back towards his previous location BUT he will not be alone: a number of cloaked nightkin will be directly behind him and at his side to check out the entrance of the area. Note that if you choose to bypass Neil and kill the nightkin at the summit by yourself, talking to him later will have no effect, since there is no one for him to fool; he will simply say, "OK. But whatever you have to do, be quick about it."
 * Use a ham radio which is located under the toppled satellite dish just across from Neil's position. You have 3 dialogue options:
 * Saying you are a big fan of the super mutants will send the remaining super mutants in the area towards your location.
 * The second option, which requires a speech check of 75 points (patch 1.01+), will cause Tabitha to say that she sentences the "Dumb-Dumbs" (non-nightkin super mutants) to death. It is also possible to pass this check with Speech 40, but for that you must know that Tabitha is paranoid, but since the flag is not set anywhere, this topic never appears (it seems that you were supposed to learn either from Neil or from Tabitha's radio broadcasts about Tabitha's paranoia, it may be cut content or a bug). Fighting will then break out between the super mutants and nightkin. The super mutants usually win the opening fight and are then attacked by more nightkin.
 * The third option will do nothing and is there only for those who change their mind.
 * If you have the means, you can of course just kill all the super mutants in the area.

At this point, you can choose to complete the quest one of three ways.
 * Enter the storage shed at the top of the mountain, where you will find a robot named Rhonda. If you decide to repair Rhonda, which requires a Science Skill of 60 points, you will receive the good ending of this quest: as you leave from the storage shed, Tabitha will appear, happy to see her robot repaired and fully functional again. She will not attack you (remaining friendly unless you attack), and you will instantly finish the quest with good Karma.
 * After doing this, you can still kill Tabitha and Rhonda and loot their corpses with no Karma penalty. You can also free Raul without Tabitha going hostile.
 * Enter the broadcast building instead and simply kill Tabitha. This carries no Karma penalty.
 * If you have a Science Skill of 25, you can hack Tabitha's personal computer (it doesn't have a special name, being simply labeled terminal). The last entry in this terminal says that Tabitha hides a second key to her personal room (where you can find her) below the stairs leading to her room.
 * Enter the prison building and release Raul.
 * The building has 2 terminals, one opened and one locked (100 Science), and a door that requires a key. The first terminal contains Raul's diary; reading Entry 6 will reveal the password (123456789) for the other terminal. The second terminal will now open the door. After talking to Raul inside and setting him free, Tabitha along with 2 nightkin will engage the Courier as soon as they leave the building, screaming "No! I won't let you have my Raul!". Killing her will complete the mission.
