I'm still not really buying the whole existence of the Confederacy because some woman with mental problems didn't go on a spaceflight to find some microbes that helped save the ozone layer or whatnot 400 years before. Since Q was actively screwing around in 2024 and hindering Picard and Co.'s attempts to get Renee on that spaceship, it seem pretty clear that this was nothing more than like when he sent Picard to that fake courtroom in the 21st century. Q ultimately created this fake timeline and had the power to erase it just as quickly. Which means that the entire need for Picard to go back in time was pointless. Q was just fucking with Picard, and ultimately didn't learn a thing from his interactions with Picard for the seven years or TNG. An utterly stupid premise and a waste of John DeLancie's talents.
