does anyone not find it odd the Nikki's father remarried so fast after his wifes horrible death and daughter getting life in prison for killing her.... was he at church???

Yes. I thought that was odd as well considering how long they were married.

Might have been cheating on his wife when she was alive. That girl really had a pretty bad plan for killing her mom, and I don't think anyone with good sense would have came up with a plan like hers.
