Interesting.
The Moon in this case is 5 degrees behind the Sun, both in the 11th house of Cancer.
It's a relationship reconciliation question, no immediate consideration of secrets (none on my part!).
The Moon isn't a primary significator in either case so I won't worry about it too much.
I found this:
'The debate on how combustion affects a planet in that planet's own sign (e.g. Venus combust in Taurus) is an ancient one. Treat it exactly as a mutual reception: the planet has power over the Sun by dispositing it; the Sun has power over the planet by combustion. So the combustion does not harm the planet; the idea of not being able to see or be seen still remains, however'.
