Mei Wong

Mei Wong is a former slave currently residing in Rivet City. When you first meet her she comes across as being very scared, as she fears a male Slaver named Sister is also in the city, and on the lookout for her.

When you meet her, you can either choose to give her 25 Caps to purchase a gun and defend herself from Sister, or go and find Sister himself, and let him know how to find Mei Wong. Either way, Sister will vanish from the city within a few days, and you will receive a Positive or Negative Karma boost based on your actions.

If you do help Mei Wong out, she will give you the location to the Temple of the Union.
