If you do not know whether you should spill the beans or keep mum, join the club (or not). If you are caught between keeping your own counsel or confiding in someone you "should" ostensibly trust, yet are getting a funny vibe from, welcome to the dilemma of the upcoming Mercury-Pluto square (exact 4/25 at 10:50 a.m. EDT).
Mercury communicates on the road, in the air, and through the rye; Pluto communicates if and when it damn well feels like it, in its own inscrutable, relentless way, since trust and power are often major-league Issues-with-a-capital-I. The face-off between these two planets should make for some interesting fireworks (especially since Mercury is in the fire sign Aries) but also some intense burns.
Verbal manipulation or downright abuse is all too likely, so be prepared either to fight back or steer clear of any black belts in tongue karate. Any long-suffering resentment will boil over now, so if you know you're on someone's shit list and cannot avoid that person (particularly a sibling or neighbor), try to make gracious and sincere amends, even if it is long overdue. People are far more likely to obsess over perceived wrongdoings under the square, and it will be difficult not to be on the defensive.
If you find that you cannot crack an important code under this aspect, or are unable to suss out someone's true motives (including your own), take a deeeeeeep breath and come back on Thursday, when the Moon enters the intuitive water sign Cancer. Under a Mercury-Pluto square, what is hiding in plain sight may just as well be swallowed up by shadows or buried six feet under.
