Back at the precinct, Jim tells George what happened at the apartment. George indulges in a little observational humor about hot women: "One minute they're right there, the next minute they take the good couch and they're gone." And her mug shot isn't showing up in the system either. "Nobody just disappears out of thin air," George assures Jim, like they haven't already tangled with a human cloud.
Katie's visiting a sick Joshua, but the Thai soup she brought him isn't going to take care of his serum-withdrawal symptoms. Joshua refuses to go to Dr. King for more, and he also rejects Katie's suggestion of getting help from Stephanie because it involves telling her about him. He wants Katie to help him instead by trying to synthesize some serum herself. Come on, at least try the Thai soup.
JJ and Daphne have found their way to the antique dealer who used to have the locket in his window (John Kapelos, the custodian from The Breakfast Club, because they're still not done mining that movie). He's not all that willing to give them anything on who sold him the locket, supposedly because he doesn't give out that information, but I think it's because JJ's drawing of the locket is rubbish anyway. Daphne steps in with a "please" -- along with that pushing sound effect that's getting so familiar, as well as that stare she does that makes her eyes seem even farther apart. Suddenly the proprietor comes over all forthcoming, and goes to get them the cancelled check he paid for the locket with. Tractor beam deactivated!
