Not too many votes yet but even now there are 2 Leos to 1 Aries. My partner is a Leo and we're both pretty stubborn. Unusually though we also choose to avoid conflict so compromise or talk things out when stubborness would normally crop up.
You have an contrascia relationship between the signs. I tend to read this as a relationship where the northern sign (in this case Leo) tends to subsume and seem to dominate the southern sign while being transformed by it.
