In the latest episode of HUMANS, Anatole comes to the Hawkins home and forces Laura to make a choice: kill a random old man from off the street, or kill Sam.

"In his mind, he's doing that to expose the hypocrisy of any human who claims to be a friend of the Synths," says co-creator and executive producer Sam Vincent. "What we were trying to do there is examine just how sort of damaging that kind of fanaticism can be, because what Anatole wants is nothing less than ideological perfection, and ideological perfection eludes everyone but the fanatic."

The choice has a profound effect on Laura. "She was utterly humiliated by that," says Katherine Parkinson. "It was fascinating to actually put her in that situation and to not come away as you might expect."

Plus, the cast and creators talk about Leo's tense relationship with his father, and why he's struggling with the idea of being a father himself. Click here to watch the cast and creators go inside the episode.
