How interesting is it when someone is being killed that Jade is no where to be seen? Yes, Lewis must have some reason to be the killer..but, come on..Jade has it in for Maddie. They never got alone, period. She wants Will for herself and for his money. She wanted to fit in with the Snyders for a so called "family" she never had. But, in reality she wanted the money. She is great at lying, we all found that out. So, my thought is from the get go of this long on going storyline of the killer/slasher is that it is Jade. She saw Maddie go nuts slashing Lias' car and went with it.
