I am guessing they planned a lot more follow-up drama regarding Cristal's miscarriage/Mark's murder, but it was all tossed out when NS asked to leave. Cristal had one line where she voiced her belief (which seemed sincere when she said it) that her family had Mark killed, but she soon fell into line against Mac (was that this name?) soon after with no explanation. She just showed up to hawk a loogie in Mac's bashed-in face. It was as if the show had wanted to stretch it out with a whodunit, but had to tie it up quickly (and apparently throw it in the lake). I should have been suspicious because it isn't typical for Alexis's efforts at covering her tracks to be so....successful.
