In 2370, the Prytt Security Ministry abducted Captain Jean-Luc Picard and Doctor Beverly Crusher and implanted them with psi-wave devices, under the false impression that the Federation was conspiring with the Kes against them. They hoped to extract information about this supposed plot once the devices were calibrated, but Kes agents were successful in providing Dr. Crusher with her tricorder and an escape route. As the two wandered Kesprytt III, they discovered that the devices were transmitting their thoughts to one another. Eventually, both learned they had each been carrying romantic feelings for one another but were too afraid to admit.
