Season 2, Episode 5 of “Star Trek: Picard” finds the crew of the La Sirena in the 21st century, trying to stop Q (John de Lancie) from altering the past to create a hellish future. With the help of The Watcher (Orla Brady) and his crew, Admiral Picard (Patrick Stewart) now knows that a certain space mission to Europa is vital.

Picard’s ancestor Renee Picard (Penelope Mitchell) is an astronaut on the mission, and Q poses as a therapist to convince her not to go. Brent Spiner returns as Doctor Adam Soongh, whose daughter Corey (Isa Briones) has a disorder that causes sunlight to “turn her blood to poison.” Q gets Soongh to serve him in return for a cure for Corey’s illness.

Q, who was once a powerful demigod, reveals to Dr. Soongh that “I have discovered of late that I have certain limitations” — his power is waning, which delivers the “different kind of Q” that John de Lancie once promised. This explains why, by the end of this episode, Q hasn’t done much more than common human trickery.

Meanwhile, in order to get close to Renee Picard and stop Q from manipulating her, The Watcher, Admiral Picard, and Doctor Jurati (Alison Pill) work together to infiltrate a party celebrating the Europa mission. Jurati, however, is hiding something, which causes the last massive twist in the episode.

As it turns out, the Borg Queen — who was killed by Jurati — has implanted herself in the lonely Jurati's mind, and is now co-piloting the doctor. This is revealed when Jurati is detained by security after sneaking into the party, and the episode ends with viewers knowing the Queen may wreck the plans of Picard and his crew.
