Homestuck

We are moments before a doomsday had exploded outside of her hive. Vriska is on a tirade of “meddling” with the other trolls. So Vriska is now chatting with Terezi. Terezi is now on the roof of her treehive, she is battling imps with a more battle ready version of her cane. She now has glasses that project a holographic screen so she can chat hands free. I’m not sure how she is seeing that screen.

Vriska tells Terezi that she is terminating their truce for the duration of the game. The truce was an agreement between them to not back stab each other. For Vriska this included not using her powers on anyone who didn't deserve it. This is apparently related to whatever happened to Aradia. Terezi mentions that whatever Vriska did to her broke Aradia’s brain. This implies that Vriska potentially murdered Aradia somehow. Vriska feels the gift she is going to give Aradia, a robot made by Equius, will absolve her of whatever it is she did. Terezi was the other half of “Team scourge”. Terezi believed they were taking “bad guys” to Vriska’s spider lusus to eat. But Vriska was just feeding anyone to it. Terezi was very good at breaking people down and using headgames. Manipulation without powers is something Vriska finds powerful. Vriska then just lambasts Terezi for not offering any kind of forgiveness or trust. The convo ends with Vriska hearing an explosion and avalanche outside. This was the doomsday device going off.

We flashback to just shortly after Vriska breaks Travos’s spine. We see Terezi, she isn't wearing the red glasses so this is from before she had been blinded. Her room looks more like Vriska’s with a FLARP poster, character sheets on the wall and some dice on her desk. Terezi is chatting with Aradia about Travos. Aradia is mad about the incident. She suspects Equius will never give Travos prosthetics out of hate for his blood color. She wants vengeance and to make Vriska pay. Apparently Aradia is immune to Vriska’s powers. But, Terezi warns her against taking action, powers or not Vriska is still dangerous. They also mentioned that they failed to help Travos because they were distracted. Someone associated with Vriska prevented them from coming to his aid. Someone who has “playing her” and is potentially even more dangerous. They agree to not take action for now.

Aradia isn't satisfied though and the voices of the dead are calling out to her loudly. She has powers of her own. She summons the ghost of all those she has fed to her spider to haunt her. Vriska is feeling all this, and it's freaking her out. The blank person reaches out to her. They tell Vriska she needs to kill Aradia. We also learn they’d played a role in hurting Travos, but the goal was to kill him as well. They tell her that all they are doing is giving Vriska the opportunities. These are things that she actually wants to do anyway. They claim they haven't convinced her to actually do anything at all.

Blank's motives are to bring about the events which will allow their employer to enter into the universe. They’re acting as a linchpin, and subtly altering things to get the desired results. Blank claims they are omniscient (knowing everything). But, they also have gaps in their knowledge. This doesn't make much sense. But he seems to know a lot of things Vriska doesn't so she has to believe him.

Vriska, plans to use someone who she only has limited control over to do what she needs to do. She messages Aradia to tell her that her boyfriend is waiting outside for her. Aradia suspects it's a trick, but falls for it anyway. It seems she was with Sollux at this time. Aradia sees Sollux floating over to her hive. He holds his glasses in one hand, and a bunch of mind honey in the other. We’ve seen that when Sollux consumes mind honey his eyes blast out a powerful laser with massively destructive potential. We can only assume that this completely atomized Aradia. This left her hive as nothing more than the foundation that she presently sits in.

Vriska had used mind control on Sollux to kill Aradia.
