WARNING: This article contains SPOILERS for Star Trek: Picard season 3, episode 4, "No Win Scenario."Jack Crusher (Ed Speelers) experienced another vision in the closing moments of Star Trek: Picard season 3, episode 4, "No Win Scenario", raising serious questions about what's happening to him. Jack's visions first began when he almost died after being exposed to poisonous gas in Picard season 3, episode 3, "Seventeen Seconds". Among the images he saw were vein-like red branches, an opening door, and a desolate landscape. These images returned as Jack freshened up in his quarters at the end of "No Win Scenario", suggesting that the visions are something more than the result of his near-death experience.
It's possible that the answer to what's causing Jack's visions in Star Trek: Picard season 3 is also the answer to why Captain Vadic (Amanda Plummer) has been chasing him and his mother, Doctor Beverly Crusher (Gates McFadden) across the universe. Therefore, understanding what's happening to Jack could reveal the larger plot against Starfleet by Vadic and the Changeling schism. Here's every possible explanation for what's happening to Jack in Picard season 3, and what it could mean for the main storyline.
