Red and Edge find themselves under the brutal watch of Underfell's King, who only becomes more and violent over time. As Red finds himself struggling to stay afloat, he imagines a happier place- where he and Edge got along better and were able to go home safe. In a moment of desperation- he tries to port away to this imaginary place-
only to find a skeleton in a blue jacket looking at him with concern.
Maybe there was somewhere for him.
