Now let's look at the progressions first. This is the secondary progressed chart.
Let's have a look at the solar arc progressed chart.
Natally, Stallone has a Uranus/North Node conjunction. This conjunction in the solar arc progressed chart is right on natal Venus, implying something sudden and unexpected (Uranus) and fated (North Node) regarding children (Venus) is on the cards.
The not relocated solar return chart.
This is very graphic. Venus (children) is angular conjunct Jupiter in detriment (ruler of the natal turned 8th house - 8th from the 5th - of the death of children) and also conjunct the South Node. The SR Ascendant is conjunct the natal 12th house cusp (the turned 8th) and the Sun is in the 8th house of death. Mars, the SR 12th house ruler, is in detriment and angular.
The lunar return chart.
The Moon is in the 5th house of children EXACTLY conjunct Saturn. The emphasis is on children for this month. Saturn is the lunar return's 8th house ruler. The Venus/Jupiter conjunction of the SR chart is in the 12th house, the turned 8th house (death of children). Mars is exactly on the 5th house cusp.The sign of Taurus, the natal 5th house sign, is on the cusp of the 12th house (death of children). Venus is co-ruler of the 5th house (the sign of Libra intercepted in the 5th) and it is located in the 12th house. In fact, Venus is both ruler of the 12th house and co-ruler of the 5th.
Of all the above charts, it is the solar return chart that actually spells out the event, but if we didn't have any concurring testimonies from the other charts, perhaps nothing of the sort would have happened.
