Suicide Mission.

Karkat's blood color starts to fill in his eyes and betrays him. He starts to realize this and tried to hide them as much as possible, yet the high bloods eventually figure out his blood color. Instead of culling karkat like they normally do to most mutants, they exile them to a unknown planet called earth. The only thing the trolls know about earth is that it's populated about an alien species called humans, and they are in war with them. His friends learn about the high bloods plans and attempt to stop it, but it was already too late. Karkat learns that his stay on earth isn't so pleasant.

Will karkat's friends go down to earth to save him from his torture? or will karkat find some humans that will make his stay on earth worth while?
