He has developed a weird, half-innocent sense of humor (which means he could probably say things and make jokes that would make others feel uncomfortable by accident.) He doesn't want people to be scared of him, so he tries as hard as he can to be nice. Blueberror is DEFINITELY messed up. He remains friendly, but sometimes he makes slightly crazy comments or looks like he's going crazy. He still longs for friends or any contact with another person, having been alone for so long with no escape.
