These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Everyman HYBRID
Alternate Character Interpretation: The Slender Man, as always. Many speculate that he's trying (and failing) to communicate with cast rather than fuck with them. On the other hand, he seems to be an accomplice in many of HABIT's murders (although we only really have HABIT's word on that).
Is Corenthal beyond our dimension, trying to help the boys? Or ... is he a puppet of HABIT?
Angst? What Angst?: While early on the guys struggled to keep up appearances while clearly losing their grips, these days they're pretty calm whenever terrible shit isn't happening at that very moment. They even still refer to their viewers as HYBRIDS. Even Jeff is cheering up somewhat, as evidenced from tweets and in "A Day with Green Feathers". It's unclear whether this is desensitization, a coping mechanism, simple acceptance of the Slender Man's existence, or the fact that Slendy has only just gotten started with them that's prevented them from losing it.
According to the November 26th uStream, they credit each other and their fans for keeping them sane.
As of HALLOWEEN HANGOVER, it appears that the guys, particularly Jeff, may be angsting a whole lot more than they let viewers know.
Continuity Lock-Out: With important information becoming spread across various Twitter, Tumblr and even other Youtube accounts, viewers unaware that the story extends to other media will slowly start noticing references to things they've never heard of as if it's already been discussed. The nature of an ARG exacerbates this, as there are no official notations of any such things existing. Fortunately, this confusion worked its way into the plot itself by way of the cast constantly interacting with viewers, so there's now an in-character hub for information that comes through places other than the main Youtube channel.
"Evan, if there was a girl version of you, I would date you."
In "Episode #4: Cardio & Outdoor Activities" and some hidden footage from "A Day In The Life", Vince seems to be cool with carrying Evan around on his back.
Invoked when Jeff offers to let Alex stay in his room to avoid the Rake.
Alex: There's one bed.
Evan: Looks like you guys are gonna get real cozy. I say as I'm on my knees.
Alex: I'll sleep on the floor.
Invoked in the 11/26 Ustream. Repeatedly. Evan is all over Jeff for a while there.
You could make a case for (probably) one-sided Damsel/Jessa, given how important Jessa seems to have been to Damsel.
HSQ: There's a few moments which really do induce this. For example, the episode "I'm Okay" is rather quiet, with Jeff speaking quietly into the camera, right up until an incredibly loud burst of distortion kicks in. And you'll have to turn the sound up to hear the talking...
Kudzu Plot: Many accuse EMH of this, and probably might be one of the biggest reason they have a Hatedom.
People say that the plot is spread too thin across different websites, while others think its better this way and makes it more of a Alternate Reality Game.
Jerkass Woobie: It's hard not to feel bad for Alex now that he's seen the Rake. What we learn from the Ustream makes it worse: his and Jeff's parents are dead, but he frequently pretends they're not. He even has a cassette tape of his mother's voice which he uses to see if he is "allowed" to do things.
Launcher of a Thousand Ships: Evan seems to be this for the fandom (Evan/Damsel, Evan/Vince, Evan/Alex, Evan/Jeff, Evan/Jessie, the affection various fandom members have for him, etc.), and he knows it. The only characters he hasn't been paired up with yet seem to be Jessa, Slender Man, the Rake, and Sparky. Yet.
Speaking of Evan's knives, "Emergency Machete" is bound to be this, especially since the real Evan in an Out of Game video referenced this with "Emergency Battleaxe", which he then proceeded to use to strike a pose of him axing Noah in the face.
Have we mentioned lately that Jeff is dead?
HABIT's love of pizza. (In "A Summoning" he tells Vincent that a left a pizza for him in the oven, and in the crossover video "Severance" he kicks Noah out of his house because he's expecting a delivery pizza and doesn't want to share).
Narm: In the "May & June" video, there is one part where Alex has a sock puppet on his hand because he is pretending that it is his recently deceased dog Sparky, using an abnormal grieving process very similar to what he uses for his dead parents. Even though this is supposed to be a disturbing scene, the sock puppet just looks too silly to be taken seriously.
In the last scene of "Consensus", Vinnie somehow lost control of his car, wakes up in the middle of the road with the Slender Man watching him, finds blood everywhere, looks in the mirror... and somehow he's been clean-shaven. Kind of a mood-killer there.
The Slender Man diving onto the ground to look through the basement window in episode 5. Granted, this was the fake Slendy they were using early on.
Daniel's murder at the hands of inHABITed Evan in an otherwise Nightmare Fuel laden entry.
Narm Charm: Some seem to see the sock puppet scene, while incredibly silly, still effective.
In "Joke's Over", you can hear a roar right before Slendy appears. If that's not scary enough, look at the area to the left of Slendy when he walks on camera - He hasfuckingtentacles!
Slendy's appearance in Evan's house is terrifying. A fleeting glimpse of Slendy tilting his head from side to side in a pitch-black room just before that room's door slams shut is not conducive to healthy dreaming.
Pretty much all of the second half of "Cops Checked, No Body."
The Rake's whisper when Evan goes over the Jeff and Alex's house to investigate.
The Rake attacking Jeff while he's holding the camera in "One step forward, two steps back". The fact that we never really see it that clearly makes it that much more terrifying. Not to mention what it did to Evan's arm.
May & June gives us our first glimpse of the Rake up close. From what we can see, it seems to avert the Special Effects Failure mentioned below in a suitably creepy way.
The voicemail on Damsel's phone in "December & early January."
Nightmare Retardant: In a way; in "dot dash," there are clips where it seems someone is filming murders or something. It becomes hilariously narmy, though, if you interpret it as Slendy stole Jeff's camera and went to get his boogie on.
There's also the fact that most commenters have fun with the videos, interpreting Slendy's actions as just wanting to get ripped and so on. Looking at them all, it becomes pretty obvious why Marble Hornets disables comments.
Oh, and if Jeff is reading this, tell Evan TV Tropes doesn't hate him.
Paranoia Fuel: The Rake likes to come to his victims while they sleep. Probably gets a kick out of when they wake up and see the grey disfigured monstrosity sitting on their beds. Even worse, he can claw the hell out of your arms without you waking up until later.
Shipping: The fandom's single favorite activity. As mentioned above Evan's a favorite (particularly Vince/Evan), but they ship most anyone to most anyone else. Of note is how they have started to ship other fans with the cast (Evan again, and a particular fan with Damsel), and even fans to each other.
A certain WMG will point you to an early point in the Slender Man mythos that clearly states that Slender Man is capable of melting his victims into mist.
It is also worth noting that there are many instances of blood looking very convincing, so as the WMG says it may not even represent blood.
This troper never had a problem with it, seeing as blood isn't the only liquid that can come out of a mutilated body...
Avoiding this is probably the reason The Rake hasn't appeared onscreen up close, considering the one time we did see it it looked like nothing more than a guy crawling on his hands and knees in one of these.
In episode 5, the power in the basement blows, but it really doesn't much look or sound like it. Bulbs tend to pop when blown, and while they did make it look like there was a bright flash, it very obviously was done through editing, as the light just flashes on the screen and doesn't bounce off of anything in the room the way light should. The lack of any light coming in through the basement window (meaning we get a totally black screen) is probably the most obvious evidence - which is odd, as that base would have been the easiest to cover simply by filming in the dark briefly. This last one, at least, might be explained by camera limitations - many small cameras won't pick up anything if the light's too low, regardless of what the human eye can manage to see.
Squick: Vincent cutting open the hanging bags in the woods, during "Joke's Over".
What the dialogue in Corenthal's report about Fairmount Vince can imply. "He lit a small candle and told us that we were going to explore a hidden cove". This might actually be Nightmare Fuel too.
Uncanny Valley: In "Joke's Over," if you watch closely enough, you can make out Slender Man's tentacles. They're clearly fake props, because they don't move at all, they remain completely static in relation to where he turns. Instead of being a Special Effects Failure, it has this effect instead, and makes the sight more unnerving than it already is.
The Rake, possibly even more so than Slender Man. He evidently has a pair of horrible, empty eyes that make Slender Man's facelessness seem comforting by comparison.
Near the beginning of "May & June" we see a close up of The Rake it looks amazingly terrifying.
What an Idiot: You have to admit it, charging Slender Man with a baseball bat is pretty dumb. Or possibly just insane. At any rate, it's a wonder Evan's still alive.
Given that the Trope Codefier for the Slender Man Mythos, Marble Hornets, primarily features Slendy standing around and doing nothing, with most other portrayals following suit, it's understandable that a person might think that the guy who hangs around watching from a distance before vanishing quickly maybe isn't such a great hand in a fight.
Now we have Vinny even considering trying to summon HABIT.
He does so, and HABIT spends much of the video berating him for having such a dumb idea, and because of his stupidity he is going to be killed in an uncreative manner instead of getting a "fun death".
After luring people over for HABIT to kill, Vinny just wants to go and asks HABIT to unlock the front door. HABIT does so. Vinny then proceeds to just stand in the open doorway, back to HABIT, looking at the outside long enough for HABIT to walk up behind him and knock him out. Give that man a Darwin Award.
Although to be fair the door doesn't open unless HABIT lets it so he might not have had much choice.
The Woobie: If Vincent from the Bag is really "our" Vinny, then this is a massive understatement.
Jeff in "I'm Okay" and more recently in "Ryan & THESEVENTRIALSOFHABIT"
Nick, who was forced to witness the brutal murder of both his parent's at the hands of Habit, watch this same creature do god-knows-what to his sister, then inHabited and forced to kill Evan. Evan then had no choice but to kill him.
As of WAKE UP, I think Evan just became the biggest woobie in the series, if not the entire mythos. (Yes, even bigger thanTim.)
