I believe Perez and the reason Rylan asked the question was because Rylan didn't actually know that a producer had conviced Perez to stay. The producer who said it to Perez didn't expect Perez to mention that he had been asked to stay etc and certainly wasn't going to mention it to anyone else as it would have been too much of a risk (for his job), in the same way that they didn't reckon Perez would spill the beans on them (a doctor) giving him sleeping pills. Perez has (had) no reason to lie and that is one of the things I have liked about him throughout this series.
