From the perspective of World-System history, the interesting events in Episode 4 are: (1) Jane Seymore finally delivers Henry VIII an heir who will become Edward VI and ensure survival of the dynasty. At the same time, Jane Seymore's death after childbirth has opened the possibility of Henry remarrying and forming new Geoplitical alliances to counter the alliance forming between France and Spain. The search for a suitable marriage partner and powerful alliance begins Cromwell's downfall.
John Dee's future forecasts for Spain (here) and France (here) don't look particularly good (I'll discuss them in a later post) and you have already seen the forecast for England (here) and the best future doesn't have anything to do with Spain or France. Keep these in mind when you are watching Episode 4: Jenneke tomorrow night.
