Warning: SPOILERS for Star Trek: Picard Season 3, Episode 5 – "Imposters."Commander Ro Laren (Michelle Forbes) dropped a Star Trek: Picard season 3 bombshell that suggests that Admiral Kathryn Janeway (Kate Mulgrew) may have been replaced by a Changeling. In Picard season 3, episode 5, "Imposters", former Maquis member and fugitive Ro Laren is now a member of Starfleet Intelligence sent to apprehend Jack Crusher (Ed Speelers) and interrogate Admiral Jean-Luc Picard (Patrick Stewart). Unable to believe that Starfleet Intelligence would hire a former traitor, Picard believes that Ro is actually a Changeling impersonator, rather than his treasonous ex-protégé from the USS Enterprise-D.
In emotional scenes that resolve a 29-year-old TNG cliffhanger, Picard and Ro begin to trust each other again as she reveals the extent of the vast Changeling conspiracy. Ro takes Jean-Luc into her confidence to reveal that the Changelings have infiltrated Starfleet, and she's aware of at least a dozen starships with Changeling impersonators aboard. Astonished by this, Jean-Luc suggests to Ro that they should contact Admiral Janeway, but Ro shoots him down by emphasizing that she can't trust anyone. There's an implication that even the former Star Trek: Voyager Captain has been replaced by a Changeling infiltrator.
