I thought calliope is alive though. Her dreamself died so when she fell asleep she just lost control of their shared body but she isn't exactly dead but kinda like, stuck in limbo? Stuck in dreambubbles since she has no body. Maybe im confused...

No Calliope is dead. If she were still alive and Caliborn was just controlling the body them his cheeks would still be swirls and wouldn’t have filled in.
