With this new chart : Sun (Air) Moon (Air) and Venus conj. ALGOL;

Saturn & Uranus both in SAG in the 12th house; makes for erraticness or anxiety, probably, (Uranian)....in the house of karma

 

AC & MC makes for a serious natured person; and as you noted, Neptune, even in Cap, conj. the AC, would suggest with it's squares, and oppositions (even to Mars).....playing a role here as well, but I would think for different (karmic ) reasons, not just biology or the gene pool.

 

Sun in the "maximum 15th degree of intensity), in Gemini; also opposes Saturn & Uranus, so perhaps he has good reasons for being anxious?  With the oppositions here, perhaps, he is constantly being flooded by unexpected events, and Saturnine woes....karmic ones?

 

But when we look to the houses, we see Saturn & Uranus firmly entrenched into the 12th house of isolation and karmic debt; even "self-undoing", yet the Sun is in the 5th?

Actually Chiron, (causes him much pain), from whatever he is undergoing, in that 12th house entry.

 

Must be connected to his love life?

Seems his 7th  house connection says this, as well as the 5th.....

 

Best for him to revisit these karmic influences, (2nd house NN 8th hs. SN indicates a past life of sexual obsessions.....) and the SN is very tight to the moon this time around.

 

This is a karmic chart,(not that others are not,as we all are in this pot of soup together,) but as far as the playing out of these various energies, IMO.
