Season 1 Episode 10
"Evil Handmade Instrument"
The hunt for David's murderer wakens a horde of Russian sleeper agents.
Still reeling from David's murder, the team finds a thumbprint in the coded book, which unravels a network of Russian sleeper agents operating in the United States. Following a string of clues from the book, they are able to track and capture a spy. With her back against the wall, the spy confesses that the Russians have been targeting expatriates and political dissenters in the U.S. Their ultimate target is Senator Riewolt, sponsor of a bill to aid the Ukrainian military, who's scheduled to make an appearance at an expo on the Intrepid. The team races to Intrepid, where Jane (Jamie Alexander) does battle with the Russian spy who murdered David. After a brutal fight, Jane and Weller (Sullivan Stapleton) neutralize the threat - for good.
At the end of the stressful day, Zapata (Audrey Esparza) signs her letter of resignation, rather than withstand Carter's (Michael Gaston) blackmail. She won't be bugging Jane's safe house. Jane sneaks away from her handlers to wait for Weller outside his apartment. She kisses him, explaining, "I just want one minute where it's just us." But when little Sawyer interrupts, Jane heads off. She's abducted by Carter and his men no more than a block away.
Jane wakes up in a warehouse, underwater - Carter is waterboarding her, demanding to know her identity. Jane mutters, "Orion," putting Carter into a panic. Just when it seems all is lost, the man with the tree tattoo (from Jane's dream) busts in and kills Carter. He calls himself Oscar and shows Jane a video of herself claiming that everything - the tattoos, memory wipe, Kurt Weller - was all her idea. The mission is going as planned.
