My heart says she got sick of the Drama Show and bailed on purpose and is safe, happy, and just fine somewhere. My head says she encountered a wicked, twisted pervert that made her go away and that happened on Monday after her mom left for work.
My GUT says, LE will uncover what really happened, who did it, when, why and how, and nail him to the wall as justice is served (and my heart goes out to her mom, because God knows, she's going to need it). My gut also says it won't be much longer before we all know what really happened that Monday.
I could be entirely off base... but I don't think so. Time will tell. Moo & all that.
