The team set out to destroy the Biosyn records and encounter a slight problem. Actually, a series of very large problems, most of them with fangs.

Chaos Theory has always had a good sense of humour, and this episode lets it fly in some of the darkest ways. The kids, and they are basically just kids, are set loose in a compound full of carnivorous dinosaurs by a guilt ridden scientist who doesn’t bother telling them the records they’re looking for could be in one of several locations. For anyone else this would be a disaster, for these six, it’s Tuesday.

The exhausted competency of the main characters doesn’t save them from peril though. There’s a great, staggered pursuit that defines the episode along with some lovely Biosyn tech that takes us back to the Crichtonian roots of the series. As a fun aside, we also get a very specific sense of timing. The kids notice Kayla and Owen’s plane this episode, with the Quetzlcoatlus closing on it. Because they’ve encountered the safety measures, they don’t think any of it but we know better. It’s a smart, elegant piece of storytelling and the episode is full of that.

In particular, the overdue talk/non-talk Kenji and Brooklynn have continued the slow reunion of the leads and is sweet and just a little broken as all these characters are. It also reminds us once again that Kenji is a mile away from the arrogant hothead at the start of the series and grounded in a way that helps ground the entire series.

Best of all though is the team getting and destroying the data and… realising it’s kind of dull. So, this group of brilliant, hyper-traumatised survivors shove the server off its platform and set fire to it. Because that’s what you do with evil dinosaur science.

Verdict: Great work kids! And a great episode too. 9/10
