What exactly is up with Sollux? His deaths got confusing.

Yeah they are and we never get an explanation for how they work. But basically, Sollux died early on, and then he died again getting the Meteor to the green sun, but I guess he only half died probably something to do with his 2 dreamselves. So he was blind in one eye and a ghost in the other.

Then pre-retcon when Erisolsprite was made, Sollux’s ghost half went to be Erisol so then he was 100% alive again and blind in both eyes.
