"Ghostbur has been in limbo for about half a year now and I promise you he is scrunching his eyes up real tight and imagining someone came back for him and he’s safe and at home with friend"

"Ghostbur is at the train station. However it’s darker, damper and every now and then he gets flashes of text on the dot matrix displays saying in written words what everyone he loves is saying about Alivebur’s return. Phil’s one broke his heart"

Different user 1: "So - is ghostbur eventually going to forget why he's even at the station?"

Wilbur: "He won’t. He’ll never forget how he failed Tommy that day."

Different user 2: "Is Phantommy/Ghostinnit present in Limbo?"

Wilbur: "Ghostbur is alone"

And the final, most devastating comment of all:

"I have no future plans for ghostbur. His current situation is his final one"
