I think what Mod A was trying to say was they probably age until they’re done with puberty and then stop.

Yes, No. Ascend on your bed, your dreamself becomes the main you. You ascend via your slab you remain you but your other selves die

No. Vriska’s clock was destroyed and she remained very much conditionally immortal. Caliborn was just special

The explosion that created the Green Sun is what killed them.  They died on their Sacrificial Slabs so they revive where they are. The trolls followed the light of the Green Sun to meet up with them out in the Furthest Ring

Not really. I’d put her in the “Chaotic Neutral” catergory

If they are awake then yes

No. The kids’ sprites match up with their dancestor. Nannasprite is the same color as Jane’s text. Jaspers is the same as roxy’s, Jadesprite is the same as Jake, so on and so forth

That is absolutely not canon

Nope, they are just called cats
