Aranea was mind controls dozens of Damara’s in dreambubbles to use their psychic abilities. 

While the Condesce has developed control over different psychic abilities through her extremely long lifespan.

That’s just how cherubs work.  The benevolent side has green blood while the malicious side has red.

Welll, Tavros/Vriska’s sprite probably won’t happen because Vriska’s alive and well.

That is a good point.  I hope we get to find out about that in the coming acts.

On Skaia the clouds showed the future.  Prospit’s moon would occasionally get close enough to Skaia that one on the moon could see the clouds.  Jade used to spend a lot of time asleep and awake on Prospit thus she saw the clouds a lot and knew certain events would happen.

No, they probably didn’t keep Gamzee prisoner.  He most likely could still go about prototyping the alpha kids’ sprites and helping Caliborn.

John made them.

Nope

All the trolls sans Aradia only prototyped their sprite once and that was with their lusus.

The trolls stopped pestering Dave and Rose because after John died that timeline became a doomed timeline and the trolls could only see the alpha timeline in Trollian so they couldn’t contact them anymore.

Lil'Cal Timeline Time

PRESCRATCH 

This Cal has the souls of Arquius, Gamzee, and Caliborn within him.

Lil’ Cal lands with Bro and lives with him.

Years pass then Dave starts playing Sburb. Cal is cut into pieces by Dave.

Bro repairs Cal and they enter the medium.

Bro is defeated by Bec Noir who take Cal as a trophy.

Bec Noir eventually enters the Trolls’ Universe where he throws Cal at an Aradiabot who is knocked through a portal into the past.

The damaged Cal is found by Aradia who gives him to Sollux who in turn gives it to Kanaya.

Kanaya repairs Cal and gives him a Felt suit.

The Trolls’ Black Queen uses Cal to ectobiologically make Doc Scratch

Sometime between when the trolls played Sgrub and arriving on the meteor Gamzee gets a hold of Cal.

Years later Gamzee sends Lil’ Cal to B2 Jack.  B2 Jack becomes cursed and turns into Jack English.

This version then dies.

POSTSCRATCH

This version of Cal is empty.

Lil’ Cal is sent back with Dirk and lives with him.

When Dirk is attacked by Crockerbots Lil’ Cal is dropped into the sea.

Years later during Caliborn’s session Cal is excavated by Gamzee and given to Caliborn.

During Caliborn’s fight with the Alpha kids Dirk traps Caliborn’s Arquiussprite and Gamzee’s souls in Lil’ Cal.

Roxy then sends Lil Cal into the void where he enters the nightmares of the unsuspecting.

Prompted by Gamzee’s chucklevoodoo Lil’ Cal enters Dave’s dreams.

Rose visits Dave’s Dreamself’s bedroom become unnerved by Cal and throws him out windows.

Rather than falling to his death be lands on Bro’s renegade rocket board which take him to the ectobiology lab.

There he is sent on the meteor alongside baby Dirk.

Repeat.
