Toni-Ann Davis

I'm really confused as to why in the first episode of season 2 it is said that leonor and her husband died along with the neighbours dog, but season 1 ended with both women moving into the house filled with sewage...i was expecting it to begin from somewhere with the two women then maybe show what caused the death of the deceased. Overall its a great show funny creative and all. But i just don't get the transition from season 1 to 2.
