Ooo, nice grand trine in fire signs, and a lofty Moon-Jupiter cnnection as part of that. Has that lordly, larger-than life potential -- but also "you play with me, you play with fire."
Lots going on in house 2. Venus is there, so likely to be possessive about his mom, his girlfriend or wife... Interesting stellium in house 3, including his Sun, so there's an easy tendency for feeling fraternal with others.
Strikes me as an attractive chart, though very fiery. Can you deal with a lot of fire or does it just exhaust you?
Can't help with the Davison chart. I always look at the two charts compared with each other when checking out relationships. EDITING TO SAY:
Hey, I just realized that was the Davison chart I was looking at when I made the comments above. Sorry, thought that was the guy's birthchart. The principles of the planets and aspects and houses should still be the same. Just apply them to your understanding of what it is that the Davison shows!
