The entire sequence of opening interactions consists of a snark-off between Dirk and Rosebot, a snark-off between Dirk and Terezi, and another snark-off between Dirk and Rosebot. There are some great lines.
TEREZI: OH MY GOD G3T OV3R YOURS3LF 1 4M B3GG1NG YOU
When Jake enters Jane's office, Brain Ghost Dirk is shown to be lying on the desk in a sexy pose. Then the validity of the images is brought into question as it corrects BGD into a more casual pose.
Vriska and Vrissy confuse each other on various parallels in their lives:
Vrissy has to explain to Vriska that the Tavros on the phone was not the Tavros she knew, but someone completely different.
Harry Anderson only gives Vrissy the go-ahead to hide the body because he thinks it's some kind of prank. When he realizes that she was telling the truth, he makes the derpy MSPA reader face. You know, the old MSPA logo?
Alt!Calliope is as ominous as ever, though her narration can occasionally be seen as The Comically Serious.
Alt!Calliope (narrating): the knight of blood falls.
cue Karkat stumbling out of his bed
Karkat gets a bit snippy about Jade's nocturnal visit:
Terezi: 1F 1 H4V3 TO H34R ON3 MOR3 T4UTOLOGY FROM 31TH3R OF YOU 1 4M GO1NG TO MOV3 TO TH3 WOODS 4ND PL4GU3 YOUR N3W SOC13TY 4S 4 H3RM1T BOG MONST3R FOR3V3R
Terezi continues to be hilarious while talking about serious topics:
Terezi: H1S T4ST3 1N 4N1M3 4LON3 1S CONC3RN1NG
Terezi: 1 D1D 3NJOY TH3 ON3 4BOUT TH3 HORS3S THOUGH
Candy!Karkat and Candy!Meenah then find out about the whole "Gamzee's dead" situation. Meenah does...not take it particularly seriously.
KARKAT: OKAY...HERE. OH. OF COURSE. CROCKER IS CLAIMING HER SON WAS KIDNAPPED AND FORCED TO PARTICIPATE. KARKAT:AND THEY’VE NAMED ME AS THE MASTERMIND. MEENAH: well we woulda taken credit for it anyway so this saves us the time MEENAH: thanks jane owe u one
Then Karkat decides to tell Candy!John, who as usual was Locked Out of the Loop, about the entire mess. John's response? Laugh uncontrollably for several minutes for the first time in years.
Harry Anderson starts out by worrying about what Roxy will think, before insisting that he is freaking out exactly as much as is still cool. (As a side note, all his phone ringtones are from things like Cats.)
Harry Anderson: i'm not allowed ONE vriska in my bedroom. i don't even want to THINK about how much trouble i'll be in if she finds out i had TWO of them up there. Vriska: Hahahahahahahaha oh my god.
Vrissy, meanwhile, puts her energy into 1) being mad that people are stealing her social media clout and 2) getting jealous that Vriska is talking to Harry Anderson and not her.
Tavros tries to pull the old Rose Lalonde, Amateur Therapist thing on Vrissy and fails.
John shows up and, while naturally insisting that he is very proud of his son, also provides constructive criticism on Harry Anderson's prank.
JOHN: and you should probably have steered clear of such a blatant nod to weekend at bernie's without seriously planning some of the logistics in advance. JOHN: i know that they make it seem so easy in that movie, but it's important to remember that not everything on the big screen translates easily to real life. JOHN:ESPECIALLY when dead bodies and clowns are concerned.
Jade's Rebel Scout costume has toe beans on the palms of its gloves.
Jade's report is along the lines of "I was too late, they've taken her," which, since Rose and Kanaya were freaking out about their daughter, does not lighten the mood...until...
Jade: THEY'VE TAKEN YIFFY! Kanaya: [boggles]
Everyone and their aunt calls John out for wearing his God Tier duds, because he hasn't resized them since he was a teenager and they absolutely do not fit him properly.
In the next update, Yiffy is revealed to be Jade and Rose's secret daughter (meaning that she's the half-sister Vrissy never knew she had). Her fully name? Yiffany Longstocking Lalonde Harley.
Said name came about due to a very complex game of Irony chicken and stubbornness at levels so pretentious and ironic that it would leave even the Striders envious at the many levels of bullshit. Even better, they then found out they couldn't even change it without going into red tape hell due to the complex and circular carapacian paperwork required to change it to the point that leaving Yiffy a secret was the better option.
Jane is having trouble crafting a eulogy for Gamzee because deep down she hated his guts. When she goes off on a bit of a rant about the cruelty and barbarism of trolls:
Jake: Could i have that once more sans the raci— Jake:I mean, Jake: In Layman's Terms? Jane: Don't worry your pretty little head about it. Jane: This is politics, Jakey. Jane: Lying through your two front teeth about people you hate is about as good a definition as it's possible to get.
Brain Ghost Dirk calls out Jake:
Dirk: All I'm saying is that this is full-blown, bona fide evil minion behaviour you're getting up to.
Vrissy's impromptu grievance session over Pesterchat ends abruptly when she passes out mid-word and her message trails off into "zzzzzzzzzzz"
Like father, like son.
HARRY: i mean, i still can't believe i told vrissy and them to bring a dead celebrity to school. HARRY: what was i THINKING. JOHN: you were thinking it sounded hilarious! JOHN: but yeah, in hindsight, maybe not the best call. JOHN: maybe it’s genetic?
Rose roasting Jane's villain speech.
Turns out, Roxy was there back in chapter 12 when Dave and Karkat kissed.
