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: Superego
Epileptic Trees: Are they dead? Are they in a coma? Are the characters all fragments of one person? Is the hospital a big therapy session? Maybe the hospital is EVERYONE'S MINDS!Who knows?!
It's gotten to the point where a WMG page was created for this comic.
Fridge Brilliance: The demonic voice speaking to Sam while he was in the White Void Room seemed nonsensical and spoke in sn incomprehensible mish-mash of letters and symbols. As noted under Subliminal Seduction on the main page, however, the gibberish is actually a code. So why was the voice speaking in code? Because Sam is a sysadmin and very familiar with computer codes and hacking, and the voice reflects his inner demons. In short, it was speaking the language he's most familiar with.
Memetic Mutation: "WHAT IT MEAN" has become a term for plot speculation, thanks to this post. Cherry almost says it at one point.
Sam thinking everything is a virus has become a meme amongst suggesters, due to being a paranoid sysadmin.
Ugly Cute: Sam, despite his "gremlinesque" features, is considered adorable by some of the readers.
The Woobie: Cherry is this in spades. She's very skittish and shy, and utterly collapses under stress, not to mention her near-constant self deprecation though all of that can probably be attributed to her Avoidant Personality Disorder. Seeing her cry is like a hard punch to the emotions.
