The Sun in Aries opposes Black Moon Lilith in Libra, at 25 degrees. The Sun and Aries are male archetypes, while BML and Libra are female. We have the classic male/female polarity, with a Lilith twist. "Passive" female energy is not so passive when BML is activated. The real woman (or raw issue) underneath the pretty picture emerges, in response to opposing male energy. There's also projection, so the initial identification of who the outsider/disrupter is may not be accurate.
Mercury in Taurus makes an inconjunct to Saturn Rx, at 16 degrees Sagittarius. What you think you know will be challenged by a greater authority, or fear. Mercury in Taurus can be very clamped down anyway, and the tense hit to Saturn will only enhance this. The net result could be a complete block on communication. It's best not to force your point across with this one, because you'll only experience frustration or complete denial of what you have to say.
Overall, not a great day for compromise or open dialogue.
