Karkat helps Gamzee brush his hair but the brush breaks a few times before they are done.

Gamzee has gone sober before but he didn't do anything because Karkat calmed him down before he hurt anybody.

Karkat is really small and light, and the others (mostly Sollux, Gamzee, and Dave) will pick him up and just swing him around while he screeches in horror and clings to them.

Karkat has one of the weirdest laughs ever. It's loud and weird and he "skrees" through most of it. Meenah thinks it's adorable and so every time they hang out she tickles him mercilessly.

When Karkat is grumpy, Kanaya imitates him and that cheers him up.

Tavros calls Karkat "Kat" while Karkat calls Tavros "Tavvy". No one knows except Kanaya, and she thinks it's adorable.

Once a month Karkat and Eridan secretly meet at eachother's houses and spend the entire time watching romcoms, eating copious amounts of junk food, and talking about their relationship issues. These evenings usually end with the two of them crying over Troll Titanic.
