In the latest episode of HUMANS, Karen and Sam are discovered in the Anti-Synth community of Waltringham.

Though Karen is killed by the mob, in some ways it's a victory for her. "She, through sheer force of will, manages to overcome her own programming," says co-creator and executive producer Jonathan Brackley. "It's a sad end for Karen's character, but it's actually a victory for the human within her."
