When Mulder has a seizure, the doctor tells Skinner to hold his head, while he and Fowler restrain Mulder's arms and legs. This is not medically accepted seizure procedure. Protocol dictates the seizing person be rolled onto his side and allowed to move around, with only his head supported to prevent injury, but not grabbed around the jaw in the manner that Skinner uses.

Dana Scully: Mulder, it's me. I know that you can hear me. If you can just give me some sign. I want you to know where I've been... what I found. I think that, if you know, that you could find a way to hold on. I need you to hold on. I found a key... the key... to every question that has ever been asked. It's a puzzle... but the pieces are there for us to put together and I know that they can save you if you can just hold on. Mulder... please. Hold on.

Good Season Opener
11 March 2006 | by See all my reviews

Following on from Biogenesis (Season 6 Finale), Scully desperately tries to discover the secrets of the spaceship beached on the Ivory Coast in West Africa, while Mulder lies in hospital with Skinner and a returning character hoping that they'll find a way to save him.

This mythology episode is a personal favourite of mine because it continues with an interesting topic, over how we came to exist and whether our ancestors were aliens or not.

The only let-down is Diana Fowley (played by Mimi Rogers), a character that I've never really been fond of, who goes around arguing about Mulder being her one true love and that she'll take care of him.

6/10 - Maybe not the best X-Files opener, but 'The Sixth Extinction' will manage to get your attention.
