Yes

It has been explained in canon that Meenah’s group was the Alpha and Karkat’s the Beta.  Whether or not that makes sense isn’t up to me.

Vriska’s ghost had been in the dreambubbles for a long time so while her ghost may look 13 since that’s when she died she’s actually a lot older because time works differently in the dreambubbles.  Meenah’s ghost on the other hand only recently arrived in the dreambubbles so she’s still relatively the same age.

Technically Karkat’s group is the Beta trolls.  But because everyone mixes up which group is which I just refer to them as pre-scratch or post-scratch.

 Kissing a dead person wakes up their other life.

That was the Jack from the Alpha kid session.

It was made by different people in each session but all of them are based on a technology found in the frog temple which is paradoxically created by the game and sent to the planet so that the game can be made.  So I guess technically the game makes itself?

Yes.  Then Doc Scratch beat the shit out of him.

They can’t.  Prospit is always destined to lose the war.
