After four episodes, Humans is finally starting to gel a bit better. Leo meeting with both Mattie and George in this week's episode regarding the weird coding found inside Anita was a good way to help integrate these stories. Even better though was the fact that after Leo met with them, the tales sort of went back to being their separate entities. Though George's interest is now piqued. As is Laura's. And Hobb's too, now that the DNA results for Leo have come back to reveal a match for Synth pioneer David Elster.
