Detailed walkthrough

 * 1) Speak with Frank Weathers at the Aerotech Office Park (receiving a note or 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.
 * 6) Talk with the freed Weathers family at the Old Mormon Fort if you discovered them by yourself.
 * 7) If the quest was given by Frank Weathers, return to him at Aerotech Office Park and tell him his family has been freed to conclude this mission and get Karma rewards. At this point you have choices to decide what Frank will do with his life. (See notes below).
 * 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, so 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.
 * Intervention with Frank Weathers
 * After you meet the grateful but numb Weathers family, huddled together at the Old Mormon Fort, you're prompted to return to Frank Weathers at Aerotech Office Park.
 * Frank will ask you about his family. After informing him they are still alive, the quest ends for 50 caps.
 * The dialogue continues with an intervention with Frank, who asks where they are. How the player answers, seals Frank's road to recovery or not.
 * Telling him outright (either for free or for additional caps) they are at the Old Mormon Fort causes Frank to walk away in disgust at the thought of meeting the Followers again, instead of reuniting with his family. He rationalizes his behavior on those "goodie-goodies" for "kicking him out before" from rehab, that the Followers probably would deny him entry anyway, which is questionable if you've been helping Dr. Julie Farkas. "Rehab's for chumps!" he says as he walks away to a questionable fate because he's still obviously in denial.
 * Following Speech 35 checks: Affirming him to clean-up and man up on his problems, before his family will want him back, strengthens his resolve to get sober and clean-up (for positive Karma). Following Speech 35 check negatively, abusively preying on Frank's guilt and self-worth, results in Frank committing suicide in a very graphic way (for negative Karma).
 * If you killed his family, either by letting them run free with the explosive collars, killing them yourself, or releasing the toxic barrels you can still complete the quest. Return to Frank Weathers to tell him they are dead and you will receive 100 XP.
