How Helen created her clone army
Cutter is not dead
Danny Quinn is actually working for Christine Johnson
The ARC is going to be the hub of human survival
The In Spite of a Nail scenario actually makes sense here
The anomaly that brought Cutter to the Claudia-less "present" was not the same anomaly that he took to the past.
In S4, Sarah's attempt to rescue Danny, Abby and Connor will result in her setting up the apocalypse
Connor is allergic to something in the 21st century atmosphere
Doctor Bashir is going to create the apocalypse
Mankind skipped the apocalypse.
The anomalies are not natural, but man-made.There's a very disproportionate number of anomalies in England, and connected to time periods capable of sustaining life (as opposed to the molten early Earth or post-swallowed-by-a-supernova-Earth). That's because somebody created them, and is using them to travel around for whatever reason. Whoever he/she/they is/are, they sneak through at some point when we aren't watching.
Primeval and Outcasts are in the same universe.In the future of Primeval, a catastrophe devastates the Earth, endangering humanity. A space programme to create a fleet of colony ships that will send thousands of humans to a planet in the Goldilocks zone, Carpathia, so Humanity can survive the destruction of Earth. This effort is organised by Richard Tate and Gideon Anderson, they agree that Tate will go on the first ship and manage Carpathia, while Gideon stays and manages the survivors on Earth, helped by his son Matt. CT-1 arrives on Carpathia and the colonists are overjoyed to find that there are no anomalies on the planet, so far. The colony of Forthaven is set up and a whole new race, the A Cs, are created. Terror strikes when an unknown virus, C-23 threatens the colony, killing the Presidents children. The finger of blame is pointed at the A Cs and they are ordered to be killed, however Mitchell Hoban spares them. And of course, 10 years after colonisation, the events of the series occur.
Jenny Lewis is a regeneration of the Doctor's daughterGenerated Anomaly. It's not a coincidence when it's WMG.
Claudia Brown disappeared through a crack in the universeGoing under the assumption that the crack and the anomaly are entirely separate entities, or perhaps that one is a side affect of the other. Cutter and Helen were through the anomaly when she disappeared. They came back to the other side, and everyone else had forgotten about Claudia Brown.
The Anomolies are Mini-Fringe eventsIn the Fringe episode "The Day We Died" we learn that there was a "black hole" like event in Central Park that supposedly connected to the late Paleozoic period. Maybe the anomalies are just an advance on the degradation or Primeval takes place "Over There".
April Leonard is Nick Cutter and Helen's daughterGiven how nefarious and underhand April is, she certainly acts a lot like Helen when she's trying to undermine Connor. Given that we don't know exactly how long Helen was tripping around time (the 8 years was on Cutter's end), and that Helen was working with Philip, it is entirely plausible that she could be Cutter and Helen's offspring.
Primeval and Time Bandits are in the same universe.Thus all the holes in time.
Helen Cutter is an evil Time Lord.She manipulates time to further her own agenda. She's ridiculously intelligent and manipulative and yet insane. Clearly, she looked into the Time Vortex and was driven insane.
Claudia Brown is alive and well.She just never crossed paths with the rest of the team, and is having a very boring life.
Ben (from the pilot) and Taylor (from 2.05) are cousins.They seem to share an enhanced sense of self-preservation that many other characters lack.
Primeval is somehow tied with the His Dark Materials TrilogyThink about it for a minute. Windows that open to a different place, (one a different universe, one a different time) The "spaghetti juntion" place in the episode with the Dodos is highly reminiscent of Citagazze. The device Helen uses to open anomalies is pretty damn similar to how the Subtle Knife works; you have to look around for where the anomaly needs to open, you can't just open one here there and everywhere. There is mention throughout the books of windows being left open by careless bearers. Like when Asriel breaks through at the end of Northern Lights and it causes dozens more to open naturally so the first use of the first anomaly device creates all the others that open naturally, or else there's a few created by careless "bearers". The ARC is similar to the Guild in HDM, in that they were doing research, and accidentally brought the Future Predators into being, which act like Spectres. Possibly they too were an accidental creation by anomalies?
Nick and Helen weren't together before she started traveling through the anomaliesThe Nick that we've been following in Primeval is actually a result of the meddling Helen has done with the past. Just like Claudia became Jenny. This is why Helen is so cold and manipulative towards Nick, to her he is literally not as real as the man she left in another timeline. She has become a sociopath because, from her point of view, all the people she encounters from the current timeline(s) are pale reflections of the "real" timeline that she disrupted. She's trying to "set things right" which of course means obliterating the timeline(s) that everyone else knows thus making her a villain in the eyes of everyone else.
Abby's parents are dead.Hence why she was the only one who could take care of her brother.
Oliver Leek and Christine Johnson were part of the same conspiracy.They both had the same idea of turning the future predators into weapons. Christine hired Leek to oversee the predators while she was in Jamaica so if things went wrong, she wouldn't be connected. She then turned up at the start of Series 3 to take personal control of the operation after Leek was killed. The reason the post-apocalyptic city still exists in Episode 10 even though Christine was killed the previous episode is because someone else assumed control after her.
Helen wasn't manipulating Philip because she wanted him to create New Dawn - she just wanted him to get Connor to build the prototype.What would it benefit Helen to open a huge Anomaly to a Bad Future full of predators and toxic winds? Her whole thing was trying to prevent humanity prematurely ending the world - at any cost. Unleashing that Bad Future would have done the exact opposite - wiping out all life on Earth. What she really wanted was Connor's prototype Anomaly to open, flooding the ARC - and only the ARC with Future Predators. Presumably, she believes that the ARC's meddling is what leads to the Bad Future in the first place. Matt believed this too - he just figured it was Philip specifically instead of the ARC as a whole. Clearly, Helen had slightly more information on the subject than Matt did. By destroying the ARC with Predators, she would therefore change history so that the Bad Future never came to pass, and the Predators and toxins that ravaged life on Earth never existed. As such, that future would wink out of existence, taking the Anomalies and the Predators with it, and life on Earth would continue as normal, minus the threat posed by the ARC. Way to prevent the salvation of the world, heroes.
Matt is in danger of disappearing like Claudia Brown.According to the Primeval RPG, people who are temporally threatened (at risk of having their existence erased or rewritten due to changes made to time) experience hallucinations - like the anomaly reflections and gorgonopsid that Claudia saw. Matt set events in motion that could cause the future he comes from to not happen and now he is apparently hallucinating his battered self telling him to fix it. If Matt's not careful he could be rewritten just like Claudia was.
Primeval and Doctor Who take place in the same universe.The raptors from the episode "Dinosaurs on a Spaceship" are literally the exact same raptors from Primeval.
The anomalies are created by a malfunctioning TARDIS somewhere in England.Even though it's confirmed anomalies exist outside of England, there's a hugely disproportionate number occurring in England. Buried somewhere there for millions of years is a forgotten TARDIS, and whenever the Earth's magnetic poles shift, it opens millions of temporal anomalies. It could even be the final resting place of the Doctor's TARDIS itself, judging by the Doctor's love of twenty-first century England.
