If Episodes 19A and B are anything to go by, Cecil and Kevin have pictures of themselves on their desks. Anyone would think this is strange, because why would you have a picture of yourself on your desk? Neither character has ever shown any narcissistic tendencies. Then you remember that Cecil -and in turn Kevin- sometimes doubts his own existence. Perhaps the photos of themselves are meant to remind them that they are, in fact, real.
Or the two photographs showed Cecil or Kevin with someone else, a friend or family member, and the narrator fixated on the person in the photo who looked identical to them because, hey, wouldn't you?
In one episode, Cecil advises the citizens to keep a photo album with them in case of memory loss, so maybe he and Kevin keep a photo of themselves in case they forget who they are?
It's been recently revealed in Episode 33 that Cecil keeps the mirror in station's the men's bathroom covered due to a weird "flickering" movement that appears when he looks at a mirror sometime after he obtains a tape recorder, which may or may not have hurt him at one point. Who's to say he doesn't do that in his house too, if he even has any? And if that's the case, what's the best way to know what you look like without using a mirror again? Oh that's right, photographs.
Also in Episodes 19A and B, one might not notice on the first listen but "The Weather" for both episodes is the same song, performed quite differently by two different bands (The Ventura Klezmer Band, then Disparition).
In Episode 25, Carlos says, "Sometimes things seem so strange or malevolent, and then you find that underneath it was something else altogether. Something pure and innocent." This could just be a statement about Carlos' changing attitude towards the entire town, but since Cecil and Carlos start dating shortly afterward it's also an apt metaphor for Carlos discovering that he's misread Cecil's intentions and is no longer conflicted about them.
Why do we hear so little of Strexcorp's takeover until episode 36? Because in episode 36, Cecil's supervisor Daniel breaks down and they can't stop him from hinting during the show. Until they shut him down, that is.
Fanon example: When Cecil is not depicted as blond, he is commonly depicted as Native American. This offers an excellent explanation for his hatred of the Apache Tracker; the racism is unbearable enough, but if Cecil is Native American, then AT's racism would be very personally offensive to him (and indeed, he is more hostile toward AT for being racist toward Native Americans than Mayor Pamela Winchell for being racist against dragons).
In Episode 19B, Vanessa and her double were building a shelf, but it collapsed. We know from that episode what materials Desert Bluffs are using to made things, and Kevin said they had no replacement parts. Desert Bluffs is all about productivity. One of the Vanessas was hurt and so couldnít work to full capacity. Strex Corp donít have room for unproductive people. What do you think the other Vanessa finished that shelf with? Kevin didnít spell it out on the radio because everyone who lives there would have known what he meant.
In episode 32, Cecil ends the broadcast on a rather alarming note: StrexCorp has bought Night Vale Community Radio and seem to be invading Night Vale. Cecil says that "everything is perfectly...safe", sounding more uncertain and nervous than he's been since The Sandstorm part B. And the worst part? His closing statements:
In episode 33, Cecil finds some cassette tapes he made as a teenager, which he doesn't remember making. They reveal, among other things, that he once had a brother, that he interned at NVCR, and that his mother and brother vanished shortly after he started at the radio station. Adult Cecil had no recollection of any of this, and—genuinely unnerved—destroyed the cassette.
Pamela Winchell in general. She's completely and dangerously insane, disturbingly violent, she apparently tortures people for no reason...and Night Vale voted her into office. This can't simply be a case of "oh, Night Vale's just that weird". Night Vale may be an Eldritch Location, but its citizens aren't so far gone that they'll permit everything and even they think that Mayor Winchell is nuts. Not to mention that Hiram McDaniels and The Faceless Old Woman Who Secretly Lives In Your House are reasonable candidates with very good ideas, so if Winchell ran against someone then it shouldn't have been a problem of whether or not her opponent was bad, unless her opponent was worse. What could possibly have happened to get the citizens of Night Vale to elect a madwoman into office?
In The Sandstorm, Kevin notes that the Night Vale recording studio is "odd and bloodless". Cecil is horrified that the Desert Bluffs station is full of blood and gore. Is Desert Bluffs' studio normally bloody?
In episode 37, there is a Police auction of seized goods and Lot 37 is Cecil Palmer, who is bought by an unknown person (or persons). It is allowed to happen and no-one points out that this is human trafficking / slavery!
On a further note, how on earth did Lot 37 end up as seized goods? Unless Cecil was owned previously.
