The anon wondering about Dirk implying to Jane that she was related to Jake; I believe they're thinking of Dirk's explanation of the future to Jake, wherein he explains the Condesce's past and Grandma English and Dirk hints to Jake about connecting his grandma's brother who inherited the company to being Poppop Crocker, but Jake is simply too dense. No biological relation, only adopted. (page 6758)

That’s probably what they were thinking of, thank you
