Nanna: Two Nannasprites Alive.
Dad: Only Dad Crocker is Alive.

Alpha Timeline Dancestors: All Dead in the Bubbles.

Condy: Likely Dead. However, we all turned our backs on the body, and that makes me nervous.

WV: Alive, given his status of Mayor to Jane. Yes, likely still alive after 5000 years, Carapaces are like, oddly long-lived and resilient to stuff.
PM: Alive, hopefully happily married to a retired WV.
WQ: Maybe still alive??? Last we knew of her she smacked Jack. May have died during Lord Jack’s rampage. May be on Earth C.
Ms. Paint: Alive and part of the Midnight Crew. Headed to Earth C last we saw.
Jack Noir: Spades and Lord Jack are dead. De-ringed, de-armed Bec Noir still alive. Currently collared by Jane and on his way to Earth C.
HB: Dead.
DD: Likely still alive but Condy could’ve just killed him out of spite to get her ring back.
CD: Last we knew he was still alive too, but ambiguous like DD.

The Felt: All Members are alive and headed to Earth C.
Serenity the Firefly: I don’t think Fireflies live that long, sadly.
Casey the Salamander: Maybe Salamanders do live that long? Maybe she’s a Lich now.

Lord English: Either Dead for Good or Trapped in a Black Hole. Either way, it’s the end of the road for him.
Alt Calliope: Either Dead or Trapped in a Black Hole. No one will ever hear or see her ever again.

Denizens: All the Kids’ Denizens are still alive? The Session seems to still exist, and there’s a gateway between Earth C and the Session so it’s likely they can still visit, or that Jade could just as easily bring the planets with her to make up a Solar System if she wanted.
Billious Slick: Croaking happily in the middle of the Alpha Session. Hopefully not threatened by the Black Hole tearing Paradox Space apart.

Every other character not mentioned here is dead. I think that’s about it.
