To help out, consider how the 4th house is about our roots, cultural heritage, family. With Leo, it’s about confidence and satisfying our inner love (personal love, especially ones that are with others and the self). Aquarius SN points to someone who can focus greatly on differentiating the self from others, making a mark, being different. But the idea of Leo NN in the 4th is to get back in touch with fully involving the self in love from those around them. 

What are you fighting for if there’s no one loving/internal love to protect? It stems from fear and an exterior “tough” front that hides your private/inner craving to actually be accepted. So Leo NN in 4th is talking about love. Particularly familial, roots, cultural heritage and learning to be proud and confident, take it personally and involve yourself (fully) in those as well.

Perhaps it’s maintaining a warmer and healthier familial connection, the ability to play and be warmed by others. It’s to receive love from those around you by exposing and accepting who you are (vulnerabilities and all, the need to be loved, special and wanted) and to do that it also has to talk about your ability to give back and ask for it (or express it to others) as well.

Accepting the love/support not through fighting for your rights, but through opening your heart instead of closing it off due to ‘strength/drive’ to be different/rebellious. Leo NN in 4th talks about the ability to ground down and reconnect with a purpose that’s deeper than just simply societal change and objectivity (maintaining outer responsibilities/image others have of you) -- it comes down to letting go with some of your belief/front (to maintain independence) in order to fully accept being part of something and being supported/loved for who you are (not just what you manifest/do for others/yourself) as well. 

Getting to know your culture, people, roots, family (and expressing your needs/being warmer and kinder to those around you) can help with healing and internal foundation (proud/confident of where your roots are). These two things are saying you may focus alot more on protecting/fighting than actually self-fulfillment/purpose of why you fight. And thus, some internal self-evaluation and intimate heart-to-heart with your own desire/craving is important.
