Another very enjoyable episode. It's great to see more humour in the series compared to Series 1. This episode does a good job at building up the intrigue of who Beth is and whether she's an alien (although wish they'd carried that on for more of the episode).

Wasn't a fan of the acting of the guy who played the sleeper agent who shot down all those soldiers though. He seemed to play it a bit camp, and as a consequence felt as though he had stepped through from a different TV Show.
