Another great episode. It sets up the intriguing mystery well, of who is kidnapping the Weevils and for what purpose and has some strong character drama (particularly with Gwen and Rhys). The espionage stuff is quite clever. I don't buy Owen deciding to go in the cage with the Weevil though, after acknowledging how morally grey an idea the Weevil death matches are. It all feels a bit too quick for my liking.
