Too bad Sue Ellen and JR are fictional characters. I'be willing to study their natal chart (I mean astrology). I'd bet
JR's Mid heaven is loaded with a strong Mars/Pluto conjunction opposite to his Sun in house 4 ( roots, family etc) ... Or Maybe a prominent house 8 , the house of Sex, power, ambition, death, manipulation...
And Sue Ellen might have struggled her whole life with a Neptune square (or maybe opposite) to a Soleil Venus conjunction... Charisma and beauty, but a chronic blindness when it comes to love... Addictions (vodka) are related to Neptune too... If SE is Linda's age, Neptune was in Virgo in 1940. I could easily picture a Pisces Sue Ellen, Virgo rising (being born around March 11, 1940)... But with Venus in Taurus in March, no Sun / Venus conjunction possible. But we still have a very interesting Neptune / Mercury and Sun opposition (wasn't SE's mind foggy sometimes... ? With an erratic behavior and bad choices... ?)
And besides Lilith / black moon is conjunct to mercury in pisces.
A Moon in Aries / House 8 conjunct to Saturn fits SE's relationship with her mother (Moon symbolizes the mother in Astrology)
It seems perfect...
This is how I see Sue Ellen (chart in attached file)
