Steven Maeda pens 4-D which makes Reyes (Annabeth Gish) put the idea of parallel universe to the test. First airing on 9 December, 2001, the episode opens with a bit of a shocker when Reyes has her throat slit and dies in the pursuit of a serial killer, Lukesh (Dylan Haggerty), and Doggett (Robert Patrick) is shot by Lukesh with Reyes’ gun.

But when we jump past the opening credits, Reyes is fine, moving into her new apartment with some help from Doggett, when she gets a phonecall from Skinner (Mitch Pileggi) – Doggett has been shot and is in critical condition. The Doggett she’s talking to disappears, and she’s left to wonder what the hell is going on, especially when she comes under suspicion of shooting her own partner – it was her gun after all, and a resident of the area, Lukesh, said that she shot Doggett.

Can Reyes figure out what is going on, and will she have the strength of her beliefs if an opportunity to save Doggett’s life is revealed?

Smart, entertaining, and showing Brad (Cary Elwes) working as part of the team, while also working to firm up his authority position, this episode adds some nice depth to the working relationship of Doggett and Reyes, and gives Brad a solid action beat.

I quite liked this one, and got quite caught up in it. I do love stories of parallel universes and temporal shenanigans. I also like that Doggett, while laid up in the hospital bed not only gave out important information, but also believed in Reyes’ theory, enough to encourage her to do what she had to do.

Lord of the Flies was written by Thomas Schnauz and first aired on 16 December, 2001. A story about acceptance and being different as seen through the eyes of teenagers.

Reyes, and Doggett, with some help from Scully (Gillian Anderson) investigate a case of a strange death. A teenaged boy, involved in a stupid prank and stunt show ends up dead, his skull collapsed by flies feeding on him from the inside.

As the agents investigate, the trail leads to a young loner, a social outcast, named Dylan (Hank Harris), whose mother (Jane Lynch) is the high school principal – making his social standing all the worse. He has eyes for his childhood friend, Nataile (Samaire Armstrong), but his mother keeps warning him off from her, and others, saying they don’t understand him and that she’s trying to keep him safe.

As the trio of agents dive deeper, they are joined by an over eager, and over tanned entomologist, Rocky Bronzino (Michael Wiseman). But as the case ramps up, and some of the local students are attacked, none of them are really prepared for where the case leads.

Alternately funny and creepy (even a touch scary) this one entertains, and shows that the truth is (still) out there…
