What important things has Johnny learned from his visit to the Lytes?

As he is leaving, Johnny speaks to Mrs. Bessie, the Lytes’ housekeeper. She says that the Lytes are going to Milton for the summer, but they will probably leave early because the Sons of Liberty are planning to tar and feather Merchant Lyte. It turns out that Mrs. Bessie is secretly a Whig and has been working with Sam Adams for years.
