Cherry

Cherry is a girl living at Dukov's Place in the Capital Wasteland. Although she denies being a whore she openly admits her trade of sexual favors for Dukov's protection.

Unmarked quest: Cherry's Freedom
If the player talks to her about Dukov, the player can convince her to follow him/her to Rivet City. If the player does this successfully (fast travel is advised), he/she will be given good Karma. As soon as you arrive on the bridge to Rivet City, she thanks you and becomes a resident of the former aircraft carrier. This unmarked Quest can also be good for evil characters. Get her outside, save, mezz, pray she doesn't blow up, then collar. Reload the save if she dies. Back to the good way of doing it:

Wait too long though, 5 in-game days or more, and you'll be greeted to a quite irate Cherry. She says, "You're a God damn liar, you said you were going to Rivet City. We've been waiting out here for over five days, I'm going back."

This quest can also be done in return for her stealing Dukov's key as part of the quest You Gotta Shoot 'Em in the Head.
