98. The Price

A friend of Simon's takes him along to see an astrophysicist, who even though discredited, has started a 'cult' organization. His name is Blake, and they all dress like Star Trek characters. Or is there something more sinister lurking? It's Ruth's first day in charge, as Julia is off sick. Only she's trying a bit too hard. Julia gets a surprise visit at home, Zara is out to get Elaine, but is totally disarmed.
