Left My Heart

Quick walkthrough
Go to Cottonwood Cove and speak to Mrs. Weathers inside of the slave pen.

Talk to Canyon runner to obtain the key for the Weathers.

Talk to one of the Weathers and set them free.

Detailed walkthrough

 * 1) Travel to Cottonwood Cove and speak to Canyon Runner near the slave cage.
 * 2) Inquire about the slaves and then talk to Mrs. Weathers inside the cage.
 * 3) Find Canyon Runner and inquire about purchasing the slaves.
 * 4) Pay 300 Caps outright, or pass the speech check (50 speech) to pay only 150 Caps.
 * 5) Enter the cage with the Weathers Slave Key and talk to any of the Weathers to set them free.


 * Alternately, if you are on bad terms with Caesar's Legion:
 * You can simply kill the guards
 * Pick the lock or take the Weathers Slave Key, talk to the slaves, and set them free.
 * The slave collars can be disarmed either using an Explosives check (50) for 50 exp each, or using the key. At a (35) Explosives check the option will be to detonate the collars and tell them "Relax, this will be over quickly" you get 35 exp but no karma loss if you choose this option. If the collars are not disarmed, talking to Mrs. Weathers with a Speech check of (50) causes them to run free, exploding on the way out.
 * A disguise is effective - sneak around the guards and speak to the Canyon Runner to purchase slaves.


 * Third Alternative
 * You do not lose faction reputation for silenced sneak kills, you can gain the key this way while still remaining friendly with all factions involved.

Disarming the collars or not, you still complete the quest.

Note

 * There is a truck perched on a precipice at Cottonwood Overlook. If the door is opened, a large number of radioactive waste barrels tumble out - killing everyone below. If the slaves have not been freed by this stage, the quest will be failed.
 * If you have the "Wild Wasteland" perk, you will see the words "Romanes Eunt Domus" painted in red letters on the wall of the Cottonwood Cove HQ. This is a reference to a scene in the movie "Monty Python's Life of Brian" where Brian (Graham Chapman) attempts to paint graffiti with the sentiment "Romans Go Home" and is schooled on his Latin by an oblivious Roman Guard (John Cleese) who insists that "Romani Ite Domum" would be the correct way to write it.
