Cherry

Cherry is a prostitute living at Dukov's Place in the Capital Wasteland. 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 adviced), he/she will be given good Karma.

Cherry can also retrieve Dukov's key for you if you are doing the You Gotta Shoot 'Em in the Head quest.
