Story number 2:
Casey Anthony Jailhouse Letters to Robyn aka Cookie
page 10 of the 11 page letter/note to Robyn/Cookie from Casey:
"You want to know something, I know that Caylee's nanny, the "real" Zenaida, the girl who was my friend for 4 years, I know in my heart that she's not responsible. And I don't blame her for not showing her face. Would you want to be sitting here with me for something you didn't do? Considering the circumstances, you technically are and it sucks. And I know this goes without saying, but outside of myself and my legal team, not a soul knows this. I was going to take Caylee and move away. Unfortunately my plans got beyond tangled when Zany wouldn't tell me where she and Cays were. I had asked her to take Cays for a few days so I could put the rest of our stuff together, money I had saved, new clothes, new everything. That's why I waited to report her missing, because she was and wasn't. I would give anything to go back to that day and to not have let Caylee out of my sight."

So, if Zany was supposed to keep Caylee for a few days why did Casey show up 'after work' to get her at all as she alleges in Story #1?
