Up until a while ago Siziem was a member of the Fuzzies and generally just hung out a lot with HP and his friends. Lately though, Siziem has discovered a talent for drawing and has become rather focused. He tends to sketch now more than talk and tends to keep his thoughts to his journal. Ms. Amelius has sent him to see the student counselor a few times but the counselor says he is just obsessed with art because of his father who is an artist, too.
If asked about his sudden change Siziem will simply say "I've grown up and I have to practice now. I don't have time to be immature anymore." HP says he has become an art snob.
