Left My Heart

Left My Heart is a side quest in Fallout: New Vegas.

Detailed walkthrough
Note: How the player goes about completing this quest depends greatly on their reputation with Caesar's Legion and somewhat on their reputation with the NCR because of the locations this quest takes place in; disguises may be in order if the player wants to avoid conflict.
 * 1) To begin the quest, speak with Frank Weathers at Aerotech Office Park, who will give you a note, or Travel to Cottonwood Cove and speak to Canyon Runner near the slave cage.
 * 2) For 300 caps, you can purchase the Weathers family from Canyon Runner. By passing a Speech check of 50 you can convince him that the family is infected with a terrible disease and he will sell them to you at a reduced price. Alternatively, the key to the Weathers' collars can be pickpocketed from Canyon Runner or looted from his corpse and the cage can be broken into.
 * 3) Enter the cage with the key and talk to any of the Weathers to set them free. If the player does not have the key or does not wish to use it to deactivate their collars, an Explosives check of 50 can be passed to do so. At the consequence of bad karma, the player can also kill the Weathers or pass an Explosives check of 35 to set their collars to explode as they leave the cage.
 * 4) If the player allows the Weathers to live, they will express their gratitude and mention that they are headed to the Old Mormon Fort. If the player mentions that it is Frank who sent him or her to find them, they will explain that they were trying to escape Frank's abuse when they were captured by the slavers and do not wish to see him again.
 * 5) If the quest was given by Frank Weathers, the player is given the objective to report to him at Aerotech Office Park. Upon informing him that his family is alive or dead, the quest ends and he rewards the player 50 caps, though the dialogue continues. At this point, the player has three options which will determine whether he chooses to change his ways and reunite with his family or not.
 * Passing one of two Speech checks of 35, the player can convince Frank to either clean up his act and reunite with his family or commit suicide, awarding good or bad karma, respectively.
 * Alternatively, the player can inform Frank of his family's whereabouts, but he will choose to not reunite with them since he is not allowed into the Old Mormon Fort and does not want to go into rehab.
