If transiting Pluto aspects your natal Saturn, that's definitely going to raise Saturn issues. From Capricorn to Leo, there's no Ptolemaic aspect. If your natal Saturn is at 24 Leo, give or take a degree or two, you would have a Pluto to Saturn quincunx right now, but that's a relatively minor thing. At most, you might have some sense of discomfort but inevitability about things, especially Saturnian sorts of things: committing to something, cutting things out of your life, aging, things like that.
But if you have Saturn in Leo, you're possibly having a Saturn opposition right now, and if not now, then definitely within the next year, because Saturn is currently transiting Aquarius. Saturn to Saturn really raises Saturn issues.
Don't blame Pluto. Blame Saturn.
