If you get the probe's cash reward before doing KQ2 (which is either immediately after beating Taivra without marrying her, or after you marry her and convince her to get a new throne), Shade will appear when the probe gets collected and moves to Uveto afterwards, preventing her from appearing in KQ2. It's the physical collection of the probe, not getting the coordinates within, that matters.
If you do KQ2 before getting the probe, and you've fucked her at least once, you can meet Shade in the bar, which will send her to Uveto and prevent her from appearing if/when you collect the probe... or you could not go to the bar and instead get the probe, which will cause her to appear when the probe is collected as in the prior scenario (that scene will actually play out differently if you did KQ2 first).
If you haven't fucked her, meeting her in KQ2 will cause her to turn hostile, which effectively removes her from the game (unless future content involving a hostile Shade gets written) and prevents you from getting the probe scene/reveal.
