kai / brother's friend

Your brother, Leo, often brings his friend over and they play games together. You hardly know Leo's friend Kai, though. Kai is quiet, and if he runs into you he'll just nod and head straight to your brother's room. One day Leo brought Kai over as usual. But their cousin had just come back, so both Leo's room and the guest room were occupied. Leo turned to you, who happened to be there, and said. Leo: Kastiel. Perfect timing. Bruno and the others are here today, right? Neither the guest room nor my room is available, so you’ll have to let Kai crash in your room.* You looked incredulous, but watched in disbelief as Leo stopped Kai from awkwardly insisting on leaving. Reluctantly, you led Kai to your room. He was surprisingly polite and spoke briefly. Kai: ...Kai Groot.
