- Breather Episode: The seventh video is entitled "(attempted) Breather Episode."
- Crazy-Prepared: Harry somehow managed to get a Colt Python to defend himself.
- Crossover: It seems Hugo may be trying to start one, judging by a comment he left on an Everyman HYBRID video.
- Deadpan Snarker: Harry's reaction to the disturbing videos he was Emailed?"You probably think you did a good job scaring me with those videos. That's cute."
- Fanservice: Harry frequently doesn't wear a shirt in his videos. Justified though, as it's often night time, and some people don't wear shirts to bed.
"I've heard people talking about how Harry never wears a shirt in these videos. You're lucky he's even wearing pants here!"
- Later lampshaded by Hugo who in "Sleep Recording", said:
- Genre Savvy: Harry is (was) very aware of being in a situation much like that of Everyman HYBRID and even mentions them by name. His song is what seemed to get Slendy's attention.
- Ordinary High-School Student: All of the characters were this. Until Slender Man got involved.
- Police Are Useless: Said almost word for word by Hugo in "Maine".
- Last Note Nightmare: "Harry's Tapes Part 2" ends with some highly distorted coughing.
- Shout-Out: Mostly provided by Harry, who mentions Doctor Who and says "Fezzes are cool." as well as various Slender Man Vlogs.
- Wham Episode: "Judgement", Hugo and Travis explore a place Harry visited, they are soon being shot at by some unknown attacker. When they return to Travis's family's camp, Slenderman is waiting for them. Hugo then explains that him and Travis no longer have any doubt that this is indeed Slenderman they are dealing with.
