The attempted replication of their technology caused chenium to leak into the River Thames, polluting it. The Medes tried to communicate with K9 and the gang, using their avatar forms to direct K9 to the source of the pollution. June shut down the project. The gangand she went to the Dauntless Prison and released the Medes, returning their technology and apologising for their capture. They cleared the pollution from the Thames and returned home.
