I can't believe it's not Sadstuck

This is the letter that Karkat left for Terezi in his Husktop. Note: this is important! READ CONFRONTATION FIRST. This is just Karkat's letter to Terezi.

It's the zombie apocalypse and everything is going anything BUT smoothly. The trolls have managed to break away from the city for a while and take refuge within, a large warehouse. Karkat has isolated himself and left everyone a little worried for him. Things are looking grim, and they have to get on the move as quick as possible. Terezi is sent to go get Karkat, but Karkat refuses to leave. http://sweetdreamshillary.tumblr.com/post/52477435795/dreaming-decadence-dementedmarionette (Here this is inspired off a post as well)

Ever since Gamzee went Sober and was shooshed by Karkat, he's been in hiding. Finally, in one of the dreambubbles, Karkat is able to confront Gamzee. He knows of the black romance that has been going on between him and Terezi, and all he wants is answers.
