Well the show has a pre-written 5 year arch which can flex to 3 or 7 depending on interest. After 3 episodes, you really should have more questions than answers. The fact that dudes' fiance had a vision and he didn't should not appear as late writing. I take it as a suggestion that there's more to come. Sure after Heroes became a joke and what the hell Lost was, it's easy to assume this will let us down too. And coming from abc, that still a huge possibility. They're a frickn' Disney franchise for fk's sake. They're as disconnected as they come.
But you have to admit, it's a very creative and daunting concept. It's got to be a lot harder to keep it all straight when the entire globes population are characters in the show. I have faith so far that there are two possibly many acceptable timelines that could unfold. The concept of knowing and thus altering the future will likely become central to the point where none of the visions come true at all. I'm really not concerned about Schrödinger's cat atm. There's enough mystery in the who, what, how and why of what's already transpired to keep around for at least this season.
Ok, plot theory.
If the device shown in Ganwar was a test run I assume it generates something seismic in the human body much like animals are connected to air pressure making them aware of coming storms or tsunamis. If this particular device compresses the nervous system in some way it's conceivable that airborne animals have either more fragile nerves or are less grounded and are killed rather than rendered unconscious.
The being collectively knocked out is less mysterious than the visions.
There's plenty of fringe science that suggests some sort of neural network in certain species such as how birds fly in formation or ants learn each others trails. The best I can guess that we too share some sort of network that was no longer grounded in time when all of its nodes crashed thus allowing a worm-hole like jump to a different present explaining why everyone flashed the same amount of time forward. But given the chaos theory, seeing it changed it and/or the vision itself was altered due to those who project more internal energy possibly explaining why the fiance saw something she really really wanted where as Demetri was less enthused.
