When they arrive in Mexico, Miranda rests in a motel room while Tom spends the day searching for Forbes. After a few incidents, Tom and Miranda locate Forbes' current home. Forbes now lives with his recent experiment named Azura, another human and alien DNA hybrid who also serves as his assistant and lover—she is sterile to prevent offspring. Forbes supports his experiment by creating half-alien facsimiles of dead pets and relatives. Forbes checks Miranda's condition and finds that Miranda has reached the end of her lifespan and will die in days; her changes to alien form are her body's way of fighting back as her human form has a weaker immune system. The only way to deny death is injecting fresh human DNA into Miranda. Miranda won't allow that to happen when she realizes it will result in the sacrifice of another human being. Again, Miranda becomes unconscious. Tom goes searching for a "donor" and is mugged by a woman in the process. Azura then incapacitates the mugger and the two bring her back to Forbes' lab, where they succeed in extending Miranda's life.
