This week's episode manages to keep up the 'wierd quotient' of this X-Files/Men in Black hybrid. The story was about a bloke who had an 'alien eye' in his possession. He got run over by a car but his 'ghost' followed Gwen's investigation into his death.

Part of the episode was set at 'Aberystwyth University'. I thought: OK, they've got the name slightly wrong but we should see some shots of the town and maybe the Old College building. Instead what we got was an interior scene which was actually filmed in the National Museum in Cardiff. I don't know whether they failed to get permission to film at the University, or whether it was too expensive, or whether they were just too plain lazy to drive to another town to film. It was a bit disappointing but didn't detract from the episode.
