Black Moon Lilith in Scorpio conjoins Juno Rx, at 0 degrees. The mistress meets the wife in a down and dirty confrontation. This is a union, but when very different energies are united, there's bound to be tension. Especially when it takes place in Scorpio, where secrets and shadows are revealed.
The underbelly of a committed relationship can be exposed, or a commitment can be strengthened by confronting the suspicion of infidelity. Juno's faithful wife can merge with Lilith, creating a woman who values her partner and her sexual independence. Or, Lilith can expose Juno's deepest fears and resentments. Juno could come face to face with her shadow - sexual manipulation, victimization or repression (in a partnership). Scorpio suggests a metaphorical death and/or resurrection of a relationship. Note Juno's Rx status - this will be a return to a past relationship issue.
BML and Juno met up previously on September 26th, 2015, in Libra. That was about balancing the two energies; finding a compromise. The conjunction in Scorpio takes it a step deeper, to complete transformation.
