I find it intriguing how this audio series is taking the opportunity to explore in more detail the relationships between characters who never got much time together in the original TV series. This one spends a lot of time with Mateusz and Tanya, two characters who followed completely different storylines on TV. In this story, Tanya is more than just the "tin dog" who knows science stuff and can hack into computers. Mateusz is more than just Charlie's love interest. Together they make an interesting investigative team. I particularly liked the awkwardness of these two essentially nice characters trying to be angry and violent towards each other in order to provoke the "monster of the week".

As far as the story goes it was another easily guessable mystery, but that's not really what it was about. It's more an exploration of an ugly side of school life, with a sprinkling of the alien rift stuff, because it's Class.
