We learned that Vriska had not only broken Travos spine, but murdered Aradia. She wasn't alone in this. This girl with the power to manipulate others had herself been manipulated. An omniscient third party with no name and white text had been messaging her. We’ve been calling them the blank one, but his name is Doc Scratch.

Scratch is in a green tinted room with a sort of old fashioned Victorian mansion vibe to it. He is wearing a pure white tux, with a green undershirt and bowtie. He’s phasing into a familiar green lightlining. His head is just a pure white sphere. Around him are 2 miniature versions of the battleground of Skaia, one the cube and the spherical version nearby. He also has a typewriter and holstered pistol on a nearby chair.

He’s described as an officer for Lord English. His job is to destroy the universe so that Lord English can come into it. This will bring about something called The Great Undoing.

If you've been paying attention you might notice guys Lord English is mentioned in the intromission sequence with the Midnight Crew. This was Spades Slick's key target but he failed to even see him. I’ll also note that Lord English’s name is spelt differently by Doc Scratch. The o in Lord, is now a gif of various pool balls.

Scratch is apparently the “First Guardian” of Alternia. This is what grants him omniscience and the ability to facilitate the planet's purpose. It mentions every planet has a first guardian and they come in various forms. He also has a specific genetic sequence in common with all other first guardians of all other planets supporting intelligent life.

I’ll point out a theory here. I probably didn't piece this together in my first read. Doc Scratch, is related to Jade's Dog Becquerel (Bec). Bec must therefore be the first guardian of earth. As Doc is guiding Vriska, Bec is guiding Jade. Though since Bec cannot speak, we dont know its motivations.

That audience isn't able to control Doc, though at this point I'm not sure the audience was even playing any character or if Hussie had taken full control. I honestly never cared. For this scene Doc's actions are only speculated on by the writer.

It seems he’s concerned Vriska is getting harder to control. He plays games with her but lately she is nearly winning, he doesn't know how. At this point he receives a message on his typewriter. This is even more concerning as his account shouldn’t even be listed, and the others shouldn't even know about him. It’s from Terezi. Before she can really say anything he deducts that she had Sollux trace his account and open the line of communication. This must still be in the context of the flashback as it seems to be shortly after the death of Aradia.

He hints that Aradia is not as dead as they think. Terezi isn't sure what to make of that but tells Doc that he will help her with revenge once she provides a tip to him. That tip is that Vriska has been cheating in the games she has been playing with him. She will tell him why in exchange for his help.

Before doing this, Terezi has one last chat with Vriska before she has doc kill her. Though not surprisingly Vriska thinks Terezi is bluffing and has no way to kill her. Terezi suggests Vriska consult her artifact. It seems before she switched to crappy magic 8 balls she had acquired an actual magic cue ball. With her 8 fold vision ability she could use it to tell the future. This Cueball of course belonged to Doc Scratch. By using it she was able to predict even his moves.

Terezi tells doc scratch about the CueBall which makes him pretty pissed off. Vriska was gazing into the cue ball for answers on how Terezi plans to kill her, the cue ball only states “I will explode in your face”. It then does so, presumably by Docs command. This destroys Virsika’s arm and her eye. Obviously as this is a flashback we know this doesn't actually kill her.
