A' course I am! Why wouldn't I be alive? Really, Kar, is that how you say hello to me after all this time?
[Figures Karkat would return and not remember him, however...]
Well, you were here before! You must have just forgotten, that happens a lot. Happened to Vriska, too, before she disappeared for the second fuckin' time as well. Usually it's because the system here glitches out. It's been too long since another troll was here with me! I've been getting real uncomfortable around all the humans that are here.
