I would think it might have to do with the 2nd/8th house axis, shared resources, finances, values, property, land, etc. This would probably also have to do with personal power between the Cancer/Capricorn axis, feminine and masculine. You are already in the nodal return at present. Saturn in Capricorn, Pluto, and South Node, I would imagine would be giving you some karmic and dharma lessons, weighing and balancing the scales.
Good way to see where you're at with soul intentions, is what was life like in North Node Capricorn/South Node Cancer back in 2010. This is reversed, but bringing similar events or situations. Also back in 2000 I believe it was in North Node Cancer/South Node Capricorn. So what kind of events happen there.
Usually there is some repeated lesson to self-master if you haven't already involving relationships. As some say. If you do things the same way, you always get the same outcome.
