CH is the mad brother you lock up when visitors come. He's like a cast member of 'One flew over the cuckoos nest'. No matter how much medication he's on it will never be enough.
Here is the fun brother. Slightly eccentric and he collects things for no apparent reason. He doesn't use most of it. You do wonder if he has a double life. Is he 'American psycho' or just a happy, slightly lonely figure living in his own tinpot world.
