Anthony Ling can vanish from Tenpenny Tower if you have robbed him before trying to convince him to live with ghouls, but after talking to Mr. Tenpenny he will be noted as convinced and you can receive the payment.
Anthony's AI packages suggest he may be homosexual. In particular, he is assigned a script package with the ID AnthonyLingFlirtWithMaleGuards, which directs him to seek out Tenpenny guards and engage them in conversation. Millicent Wellington makes a reference to him flirting with the guards in one of the random conversations she may have with her husband. She suggests, however, that Ling should find a nice girl to settle down with.
