Cindy was trying to impress upon KC that she would do whatever it took to get her to take her to Caylee. At that point, she realized KC had been lying to her, wasn't where she'd said she was, so Cindy had decided that she was through playing hide the baby. She probably thought KC would cave if she took her to the police station and produce Caylee. I really believe she didn't know that it was too late and KC couldn't produce Caylee, at least not in a form that would make Cindy happy. The police station was closed so Cindy went home, no doubt threatening to call the police again all the way if KC didn't take her to Caylee. Wonder what KC was thinking when they drove close to where she'd dumped the body. She was probably hoping that Cindy would give her another chance, another day, so that she could take off, some how, some way. This one's not much of a planner. Trapped in the house with Cindy, with the police definitely on the table, talking to Lee, she knew she had to come up with something else because her 'one more day' was probably not going to happen. Did she tell Lee? God, I hope not. I hope families don't really protect the murderers of little children. Did Cindy know? I don't think so. KC had probably been toying with a kidnapping story over at Tony's, knowing someday she'd have to explain something to someone, but she's completely disorganized and not the most complete sandwich in the basket, and she didn't have a really good story put together yet, even after she'd known for a month she might need one. She went with it anyway. What else could she do? If Mommy found out what really happend, she'd lose Mommy forever. She hated Mommy, and in a way what happened will make Mommy pay, and Mommy deserves that. What happened was really Mommy's fault any way, so it's kind of 'justice' for Mommy, but it would be the worst thing in the world to lose Mommy, so can Mommy can NEVER know. Just talk, talk and look good, sound confident. The cops are guys, right? Might work. Always did before.
