One of the great contributions to the richness of Hong Kong’s urban scene were without doubt the caged balconies that lined the elevations not only of the Walled City, but also of many of the city’s other older tenement buildings. Sadly now but a distant memory, since they were classified as illegal structures in the late 1990s and torn down, these practical and otherwise very necessary additions to life in a tiny apartment were a source of constant delight.
Wilx tortured and killed the Cain mother, which is why the entire family and Esther hold such a deep grudge against him. He didn't get any information out of her, but while he was keeping her in a cage in his basement his wife discovered her. He either had to kill the wife or she was killed trying to help the mother, but either way he blames Esther and the Cains for his wife's death, even though he killed the mother.
