Still, you can see why he would think that because none of it really made sense except in a very cliched, and frankly dumb, way.
That's the trajectory of the whole episode though. From original to cliche to stupidly cliched. It starts in an interesting place. Mutant powers and mental illness as integrated metaphors for the alienation one feels from adolescence to young adulthood.
For me, that's a great basis for an interesting dramatic series. A man who is sane until gifts that set him drastically apart from others convinces him that he's insane and then when he realizes that these are gifts, he's already traumatized to the point that he actually is insane and now has to find a way to cope. To achieve balance. That's a terrific dramatic premise.
Sure, you have to throw in the secret organizations and eccentric resistance groups, but the "evil" organization started out much more interesting. Like they could actually turn out to be more interested in helping David than Syd's team would be.
But then, they turn out to be typical Bond villains with low rent Mission Impossible death traps.
I was still interested when he was in Clockworks even though it was also pretty much a cliche and, obviously, the most well designed and comfortable mental health facility ever on television. I mean, he was much better off there than his sister's basement. Nevertheless, it felt like a Cuckoo's Nest with a Scanners twist storyline was in the offing.
But then that is blown away and they instead go for the evil secret organization angle which ends up with David again drifting into a completely new environment with whatever that Miss Peregrine style group turns out to be.
David actually doesn't take action as much as he is acted upon. The story progressed from something interesting to something confused but oddly familiar. I actually didn't feel that the episode really told a story. It barely introduced the main characters.
