Dana Cutrone asks Jackie help because her boyfriend has changed the locks on her apartment, leaving her with nowhere to go! She wants Jackie to go find him and get the new key for the place for her.
The place is in Chinatown, in a small building that has a corridor that connects Lester Street with Mulberry Alley. If you ask her boyfriend for the keys, he'll hand them over, and you'll also be able to enter the apartment and nab the Lumberjack Outfit for your Darklings. Return the key to Dana for a collectible phone number.
