Final answer:
The provided excerpt from a fictional text does not contain enough information to accurately determine which episode immediately follows Billy's recollection of Dresden without further context about the book or story.
Step-by-step explanation:
The quoted passage appears to be from a fictional text, which means that the question likely pertains to the events or characters of a novel or a story. Specifically, the passage mentions characters named Bishop Dyer, Jane, and Lassiter, as well as Milly Erne's grave. The dialogue suggests a revelation or a moment of suspense related to the reasons behind Lassiter's presence in a particular place. If this text is connected to the mention of 'Billy's recollection of Dresden,' it suggests that the narrative could involve shifts in time or perspective, or that it might be part of a larger, more complex story with multiple threads or characters.
However, without the context of which specific work this excerpt is from, it is not possible to determine the exact episode that follows Billy's recollection of Dresden. More information about the book or story in question would be required to provide an accurate response. The passage provided does not contain enough information to answer the question about the sequence of events in Billy's narrative.
