Bizarro Universe: Any object, pet, or lusus that in Homestuck were prototyped into Sprites are now the characters of this story. The reverse is also true as far as we've seen. Certain other figures from the Alpha timeline, like Maplehoof (and potentially the as-of-yet unseen Grandpa Harley) have also been repurposed.
Book Dumb: Justified with Bec, as living on a island most of his life, never went to school, no one else there to teach and had to learn by himself, with Jasper's help.
Butt Monkey: From Scarvenrot's Tumblr: Cal would throw/drag his Dave puppet down stairs in fits of jealousy/annoyance/for no reason at all, but it will bite him in the ass when Dave gets prototyped.
Cassandra Truth: TA/Wyvern tried to warn Bec not to download Sburg and not to trust GT/Stheno, but Bec brushes off her warnings and blocks her. Justified as Bec had never spoke or knew TA/Wyvern until her warning.
Feigning Intelligence: Jaspers likes to think of himself as the mature and intelligent one, but in actuality, he's a goofy kid that doesn't always know what he is talking about. He's also nowhere near as good at navigating social situations as he thinks he is.
Heroic BSOD: Jaspers' dad is devastated at the thought of Jaspers wanting to run away from home.
Jaspers goes into this when he accidentally kills Jade.
Heroes Love Dogs: Bec with his not-quite-puppy-not-quite-adult dog, Jade. Averted with Jaspers who has a cat, Rose.
G.I.R.L.: Bec's friend, GT/Stheno. Except GT is female, just not human.
Jerkass: Jaspers used to bully Bec online for his poor reading compehension, typing and gaming skills when they were eleven.
Jaspers towards his dad, all the damn time.
Jerkass Realization: When Bec called Jaspers out on his bullying, Jaspers realized what a horrible person he was. Jaspers then changed all the names of his online accounts and befriended Bec. Bec doesn't know Jaspers was the guy that bullied him.
Kitsch Collection: Quinn collects fine china dolls, her favorite are harlequins and Victorian ladies.
Metaphorgotten: Kind of; Bec's (admittedly sarcastic) metaphor about Jade's death and Jaspers' (as far as he knows) careless reaction to it eventually stops being a metaphor and quickly devolves into a Shaped Like Itself rant.
CC: like if somebody killed your mom and then brought her back to life i dont think youd be like
CC: oh yeah no everythings cool now its not like i just tried to pry my bed off of the floor to save her and got her blood all over my hands or anything
CC: nah man were okay
Nephewism: Cal is being raised by his cousin, Liv.
Nice Job Breaking It, Hero: TA warns Bec to not play SBURB because it will kill them all. Bec ignores the warnings and burns a copy of the game anyways.
No Sense of Personal Space: Squarewave gets very touchy-feely with Cal and will hug him, stand uncomfortably close to him, and touch his hair/face, even though he claims he would never invade Cal's space without his permission. When called out on this, he claims he just can't help it.
Parents as People: Colt Lalonde tries to be a good, understanding dad to Jaspers, but Jaspers doesn't quite understand his dad.
Please Wake Up: Bec tries to wake up Jade after she is accidentally crushed by Jaspers.
Real Men Wear Pink: Cal loves playing princess RPs with Quinn, plays with puppets and is jealous of Quinn's doll collection.
Security Blanket: Quinn's personal favorite doll is the ragdoll, John. She even calls him her "brother".
