Irish was sure that Britney also felt astonished about Becky's behavior. Becky attracted people's attention successfully by taking advantage of Joseph. It was natural that Britney would not let that happen.
Irish figured it out, so she spent some money to help Becky and hyped up her rumor about Joseph. Of course, it was a piece of negative news.
When Irish found the hotel manager through someone well-informed, she found that a group of people had come there, trying to discover Becky's past since people must be interested in that. But they all failed because they didn't pay enough money. Just as the old saying goes, money makes the mare go.
