It was always hard to get over someone who had died after pretending to be dead or even had died multiple times already. In this particular case, the person had only been mostly dead for an extended period of time, but it was still hard to truly realize that he was gone for good. Also, when using the word 'person,' some people could really mean to be saying 'troll.' Once more, Karkat huddled into the dreaded horn pile that he had made because some trauma from earlier in life had made it so that he couldn't sleep without them. And of ccourse he was the one having trouble adjusting to death now that he had finally managed to defeat that video game that shall remain unmentioned and hopefully dormant in the depths of human hell for the rest of eternity and beyond in every possible timeline that ever pretended to be a line even thought it was really just a bunch of silly putty that secretly wished it was silly string. And now that death was a permanent thing instead of a cop out excuse to throw memories into space, of course Karkat was stuck remembering everything that gave home night terrors and kept him from enjoying a normal life.
The horn pile was not offering the simple comforts of the time before horrors had taken over his think pan. It also wasn't offering much in the way of physical comfort either, but for some reason he couldn't just leave it and hide anywhere else. Something buzzed in the pile, reminding him of the friend who was truly gone forever and dead as a doornail in the never-ever-coming-back-ever sort of way. After digging around for a short while, the troll found a small handheld chat device with bright blue text in a little speech bubble that could only be one of one people trying to contact him. Since, ha ha, all of his other blue text typing friends were just as dead as his dead friend that he couldn't not remember at that moment. His glazed yellow eyes quickly flitted over the screen, only to finally rest and then roll up to the ceiling in a slightly exasperated manner. The friend had just asked if he was okay, and the fact that the human was asking was because he had heard about the death from his annoying red text human friend who had most likely heard it from Terezi. He wanted to be fine, and desperately wished that he could just mope in peace for about five hours before taking a cold bath and moving on just like always, but of course the weird John-human would text him a lot and the darned chat device would just buzz indefinitely for a while. So, instead of moping, the young troll angrily texted his friend for a while and lamented over the loss of such a brilliant mind as his dead friend. They then decided to hold a corpse party, but a private one so that nothing weird would go down what with bodies and crap being a strange subject. Karkat got over things after a while, with the help of some persistent friends, but the fear of playing that one game never to be mentioned again or else slipped into his dreams and haunted him until the day he inevitably died.
